1.2 Information on Laser Safety
1.2.1 Safety Information
The light source of the instrument is a laser. It is important to understand that
laser light has different properties from ordinary light sources. Laser light is
generally extremely intense due to the beam's low divergence. When
handling lasers, great care should be taken in any case to make sure that the
direct or reflected beam does not enter the eye.
NOTE!
For the detailed technical specifications, see CHAPTER 7!
General The protective measures described in the following support compliance with
the safety standards for
Laser Class 2 :
• Polytec instruments generally comply with the standards IEC and
EN 60825-1 respectively US 21 CFR 1040.10 and 1040.11 except for
deviations pursuant to Laser Notice no. 50, dated 24 June 2007.
• The optical output power of the laser beam emitted from the instrument is
less than 1mW provided the equipment is used in the manner for which it
was intended. This means that the instrument conforms with
laser class 2
and is generally very safe. It is thereby usually assumed that eyes are
protected by prevention mechanisms including the blink reflex. This
reaction offers appropriate protection under reasonably foreseeable
operating conditions. This includes the use of optical instruments for
observing the laser beam. Even when optimally focused, the laser beam
is not intense enough to harm the skin.
• The user should not attempt to open the housing of the instrument which
contains the laser unit as he could be exposed to a higher level of laser
radiation that is potentially hazardous.
• Use of controls or adjustments or performance of procedures other than
those specified here may result in hazardous radiation exposure.
Specific • An emission indicator on the scanning head indicates the activity of the
installed laser and thus the potential hazard of laser beams emitted.
• The laser is switched on using the key switch on the front-end. The key
can only be removed if the front-end and therefore also the laser is
switched off.

1 Safety Information
1.2.2 Safety Precautions
Pay attention to the following safety precautions when using the instrument:
• Only qualified and fully trained persons should be entrusted with setting
up the instrument, adjusting and operating it!
• Avoid looking directly into the laser beam with the naked eye or with the
aid of mirrors or optical instruments!
• Wear suitable laser adjustment eyewear when you have to look at the
target area of the laser beam long and hard to set it up!
• Never intentionally direct the laser beam at anyone!
• Do not use any reflective tools, watches etc. when you are working in the
beam path of the laser!
• Avoid staying in the scanning area! The laser beam can exit the scanning
head in an angle of ± 25°!
• Always close the beam shutter, before positioning the scanning head. The
beam shutter should not be opened until the scanning head has been
roughly aligned and mounted securely!
• The laser beam should be terminated at the end of its intended path
where this is practically possible.
• Instruments which are not in use should be stored in places which
unauthorized persons do not have access to.

1.3 Information on Electrical Safety
1.3.1 Safety Information
The instrument complies with the electrical protection class 1 in accordance
with the EU Directive 2006/95/ EC (Low Voltage Directive). With correct
mains connection and intended use, exposure to electric current is prevented
by the closed, grounded metal housing.
The instrument is subjected to the EU Directive 2004/108/ EC (EMC
Directive) and therefore complies with the limit values for emission and
immunity of the standards they are based on (refer also to
SECTION 7.1 and
APPENDIX C).
CAUTION!
Impairment caused by radio interference! This device is subjected to Limit Class A and
can cause radio interferences in residential areas. In this case, the user has to carry out
appropriate measures.
1.3.2 Safety Precautions
Pay attention to the following safety precautions when using the instrument:
• The instruments may only be connected up using a three-pin mains cable
to AC systems 50/60Hz with a grounded protective conductor, and a
nominal voltage of between 100V and 240V.
• Defective mains fuses may only be replaced by fuses of the same kind
with the rating given on the instrument.
• If the mains switch is not freely accessible the mains plug is used as a
separator in case of danger. This means that the mains plug needs to be
freely accessible. Otherwise an additional disconnection device must be
installed.
• The housing may not be opened when using the instrument as intended.
Opening the housing will invalidate the warranty. None of the instruments
may be operated with opened housing.
• Maintenance and repair work may only be carried out by the manufacturer
or by qualified persons authorized by the manufacturer.
• Disconnect the mains plug before you remove parts of the housing for
installation and servicing purposes.
• Existing air inlets and outlets must always be kept free to allow sufficient
cooling. If you notice that a cooling fan is not working, immediately switch
off the affected instrument.

2 Introduction
2.1 Area of Application and System Summary
The Polytec Scanning Vibrometer PSV measures the two-dimensional
distribution of vibrational velocity on the basis of laser interferometry. The
system components are shown in the following figure.
Figure 2.1: System components of the PSV-500-HM
Polytec Scanning Vibrometers consist of the basic components optics
(scanning head), electronics (front-end), junction box and control (data
management system). The components are adapted to suit the intended area
of application and can be customized by adding accessories and upgrading
the hardware. The decoders to analyze the vibrometer signal are designed as
digital wide range decoders and thus fit into the digital signal concept.
The scanning head consists of the interferometer, the scanner mirrors to
deflect the laser beam, and a video camera to visualize the measurement
object. As an option, the scanning head contains the geometry scan unit and
the CoherenceOptimizer (for the stabilization of laser modes). The PSV-A-515
digital video camera is available as an accessory. Then you can set which
video camera is being used in the software.
In the front-end the interferometer signal of the vibrometer is demodulated
using a velocity decoder and is transmitted to the PC. Synchronously to the
vibrometer data, reference channels are acquired and generator signals are
emitted. The front-end is applied for the operation as an H system and covers
bandwidths up to 100kHz.
The PSV-E-530 junction box provides the connections for the reference
channels and generator signals for the operation as an M system with
bandwidths of more than 100kHz.
The measurement data is acquired and saved in the PC. The PSV software
controls the entire measurement system and offers user-friendly functions to
evaluate the measurement data.

2.2 Signal Flow between the System Components
2.2.1 Principle
In the front-end, the high-frequency Doppler signal coming from the scanning
head is fed in the decoder. Here, the velocity information is extracted from the
signal. You can run the system either as a PSV-500-H or as a PSV-500-M. To
do so, when starting the software select the corresponding data acquisition
board: Ethernet for the operation as an H system or PCI-6110 for the
operation as an M system.
Operation as an
H system
Synchronously to the decoder, analog reference signals are acquired and
generator signals are emitted in the front-end. The digital measurement data
is exchanged with the PC via an Ethernet interface. The signal flow in the
system is shown in the following figure.
Figure 2.2: Schematic diagram of the signal flow in the PSV-500-HM (H system)
Operation as an
M system
On the junction box, analog reference signals are connected and generator
signals are emitted. The measurement data is transmitted as analog signals
to the PC. The signal flow is shown in the following figure.

2 Introduction
2.2.2 Decoder
In the PSV-500-HM the digital velocity decoder DV-04 is used. It enables very
precise and high-resolution acquisition of vibrations. With the PSV-500-H, the
decoder signals are directly transmitted digitally to the PC. With the
PSV-500-M the signals are converted into analog signals and transmitted to
the data acquisition board of the PC.
The decoder is equipped with digital tracking filters which allow undisturbed
measurements, even if the optical signals are weak.
DV-04 With 13 measurement ranges, the DV-04 velocity decoder covers the
frequency range from 0Hz to 2 MHz.
2.3 Different Operating Modes
The decoder and the filter in the front-end as well as the data acquisition
board determine the metrological properties of the PSV. Depending on the
application, there are different operating modes available. Their properties
are summarized in the following table.

3 First Steps
Inspection Please pay attention to the following steps when unpacking:
1. Check the packaging for signs of unsuitable handling during transport.
2. After unpacking, check all components for external damage (scratches,
loose screws, damaged components etc.).
3. In the case of a wrong delivery, damage or missing parts, immediately
inform your local Polytec representative, stating the serial number of the
instrument. The serial number can be found on the identification label.
You will find the identification label on the instruments (refer to
SECTION 3.3) as well as on the inside cover of this manual.
4. Carefully retain the original packaging in case you have to return the
instruments.
Install the instrument and carry out a first functional test as described in
SECTION 3.6.
3.2 Operating and Maintenance Requirements
Ambient
conditions
The instrument can be operated in dry rooms under normal climatic conditions
(refer to specifications in
CHAPTER 7). In particular the optical components are
sensitive to moisture, high temperatures, vibrations and dirt.
If you start operating the instrument after storing it in a cold environment,
allow a sufficient acclimatization period before switching it on. Avoid
condensing moisture on the optical components as a result of a rapid
temperature change.
Assembly A scanning head must not be set up provisionally but must be securely
mounted as free of vibration as possible on a stable tripod or an alternative
stable base using the mounting threads.
Cooling Remove the covers of the system cabinet, before you are operating the
instrument in the system cabinet.
Always keep the air inlets free. The distance to the wall must be at least
50mm! Provide sufficient free space under the instrument as air vents are
located there!
Cooling of the
scanning head
At ambient temperatures above 35°C (95°F) you may only operate the
scanning head if the scanning head is assembled on a tripod so that also its
bottom side is freely accessible (e.g. VIB-A-T02).
Refer also to
SECTION 7.5.1.

3-3
3 First Steps
Connecting
cables
As a general rule, the instrument may not be switched on until all connecting
cables have been connected up. Make sure that all connections are
connected properly and firmly.
Protect the connecting cables from mechanical damage and high
temperatures. The bending radius of the main cable (Umbilical) may not be
less than 120mm. We recommend a minimal bending radius of 150mm, in
order to keep the strain of the main cable as low as possible. The bending
radius of the other cables may not be less than 50mm.
Mains
connection
The mains voltage inputs of the instruments are designed as wide range
inputs and can be connected to all mains voltages with nominal values in the
range from 100V to 240V.
Warming-up The helium-neon laser will take a while to reach the optimal operating
temperature after it has been switched on. The instrument does not reach its
optimal metrological properties until a warm-up period of approx. 30 minutes.
For measurement tasks with high angular stability requirements we
recommend a warm-up period of 120 minutes. This applies especially when
you are working with imported 3D geometries.
Cleaning Clean the housing surfaces with mild detergent or disinfectant solutions. Do
not use organic solvents!
Switch off the instrument before cleaning it.
Cleaning
scanning head
Only use bellows to remove dirt such as dust on the scanner mirror.
Switch off the instrument before cleaning it.
Installation of
other
components
Hardware or software components which do not belong to the system can
damage the system or adversely affect the way the Polytec software
functions. Using them will result in the loss of warranty. If you want to install
such components, contact Polytec.
Opening the
instruments
Tampering with the instruments in any way is not necessary when using the
equipment as intended and will invalidate the warranty. Exchanging or
retrospectively installing subassemblies may only be carried out by
authorized service personnel of Polytec.
