1. Safety precautions
· Use supplyvoltage and interfaces indicated in the scanner specifications.
· In connection/disconnection of cables, the scanner power must be switched off.
· Do not use scanners in locations close to powerful light sources.
· To obtain stable results, wait about 20 minutes after scanner activation to achieve
uniform scanner warm-up.
· Scanners must be grounded.
2. CE сompliance
Laser scanners have been developed for use in industry and meet the requirements
of the following Directives:
· EU directive 2014/30/EU. Electromagnetic compatibility (EMC).
· EU directive 2011/65/EU, “RoHS“ category 9.
3. Laser safety
Scanners belong to 2M laser safety class according to IEC/EN 60825-1:2014.
Scanners make use of a c.w. 660 nm or 405 nm or 450 nm or 808 nm wavelength
semiconductor laser. Maximum output power is 10 mW. The following warning label is
placed on the scanner housing:
The following safety measures should be taken while operating the scanners:
· Do not target laser beam to humans.
· Do not disassemble the scanner.
· Avoid staring into the laser beam.
4. General information
Laser scanners are designed for non-contact measuring and checking of surface
profile, position, displacement, dimensions, sorting and sensing of technological objects,
3D models construction.
5. Structure and operating principle
Operation of the scanners is based on the principle of optical triangulation (see
Figure below).
Radiation of a semiconductor laser is formed by a lens in a line and projected to an
object. Radiation scattered from the object is collected by the lens and directed to a two-
dimensional CMOS image sensor. The image of object outline thus formed is analyzed by a
FPGA and signal processor, which calculates the distance to the object (Z-coordinate) for
each point of the set along the laser line on the object (X-coordinate). Scanners are
characterized by the beginning of the range (SMR) for Z-coordinate, measuring range (MR)
for Z-coordinate, measuring range for X-coordinate at the beginning of Z (Xsmr) and
measuring range for X-coordinate at the end of Z (Xemr).

6. Configurations, operating modes, and options
Scanners are available in the following versions:
· based on red laser, 660 nm;
· based on blue lasers (BLUE version), 405 or 450 nm;
· based on infrared laser (IR version), 808 nm.
We use different lasers due to a wide range of applications. For example, the use of
blue lasers instead of red ones is optimal for the control of shiny materials, high-
temperature objects and organic materials.
The use of scanners with lasers of different wavelengths in one measurement
system makes it possible to avoid the scanners mutual influence and greatly simplifies the
system construction.
Scanners can be equipped with a built-in heater for operation under low-
temperature conditions.
There are two operating modes in the full working range: with frequencies of 484 Hz
(profiles/second) and 938 Hz (DS mode).
In addition, you can use the ROI function, which makes it possible to increase the
working frequency of the scanner in the limited working range up to 5096 Hz and up to 6800
Hz in the DS mode.

19. "General" tab. General parameters
19.1. Image quality settings
The intensity of the reflected light entering the scanner depends on the properties of
the surface of the object under control. In turn, the value of electric signal generated by the
CMOS image sensor of the scanner depends on the time of accumulation of radiation
(exposure time). Therefore, in order to obtain optimal signal, it is necessary to set optimal
exposure time.
Since the exposure time cannot exceed the frame duration, it is necessary to set the
required frame rate (FPS parameter) before setting the exposure time.
19.1.1. Frame rate
Parameters:
Parameter
Factory value
Description
FPS
484

· ON - enabled, the scanner works in the DS mode;
· OFF - disabled, the scanner works in the standard mode.
Note: In this mode, the linearity of the scanner for Z is reduced
from ±0.05% to ±0.1% of the measuring range for Z.
To set the FPS parameter, use the slider, or enter the required value into the field
and press Enter (valid for standard operation mode, as well as for DS and ROI modes).
The maximum possible value for the current mode is shown next to the FPS field.
19.1.2. Exposure time and laser power adjustment

Description
Laser output
power, %

The output power level of the laser. Range of values: 0...100%.
Note: The power level of the laser is adjustable only in manual
mode.
Exposure time Laser brightness are set manually based on visual analysis of the
quality of the image obtained from the image sensor, and on analysis of the quality of the
resulting profile (see p. 16.).
To set the exposure time, use the slider, or enter the required value into the field and
press Enter. For convenience, you can select Profile data format - Raw profile (Section
Data stream options tab General). In this case, the Video tab simultaneously displays a
video signal and an extracted profile in coordinates of the CMOS sensor (uncalibrated
data). To enable the autoexposure mode, click the Autoexposure button. The scanner
will automatically set the optimal exposure time.

19.2. ROI settings
The ROI (region of interest) parameters control the size and position of the CMOS
sensor active area. By default, the active area covers the entire area of the sensor.
Decreasing the active area size allows to increase the scanner speed due to decreasing of
the image reading time. Resizing is possible in Z-direction only and is performed in the
CMOS sensor coordinates.

Description
ROI On/Off
OFF
Enable/disable the ROI mode:
· ON - enabled;
· OFF - disabled.
When this mode is enabled, the CMOS sensor switches to the
mode of processing a part of the active area with the ROI position
and ROI size parameters. The frequency of profiles increases
inversely with the size of the region of interest (ROI size).

ROI mode
FIXED
Control modes:
· FIXED - Manual mode. The position of the region of interest is
fixed and is determined by the ROI position parameter. The size
of the area is determined by the ROI size parameter.
· AUTO - Auto mode. The area of interest automatically moves
within the working range of the scanner in order to keep the
profile image within the boundaries of the set area. This mode
allows to work in the entire working range of the scanner with
increased speed.
Set ROI position in
FIXED mode
300
The position of the upper boundary of the region of interest in the
FIXED mode. Valid values: from 0 to (488 - ROI Size).
ROI size
64
The size of the region of interest. Valid values: from 24 to 480 with
the step of 8.
Profile points for ROI
detect
324
This parameter is active in the AUTO mode. It sets the number of
points in the profile that indicates that the profile is located within
the region of interest. If the number of points in the region of
interest is less than the specified value, the scanner automatically
switches to the profile search mode on the entire field of the CMOS
sensor (The region of interest expands to the entire CMOS sensor
with a corresponding change in speed). When the specified number
of profile points is detected, the scanner automatically returns to
the specified ROI size.
Valid number of points: from 1 to 648.
The size of the region of interest is determined by the ROI size
parameter, the ROI position parameter is changed automatically.
Example: Automatic displacement of the region of interest with keeping the profile
within the set boundaries (yellow lines).

Profile data format
Calibrated profile
Profile formats:
· Calibrated profile - transfer of calibrated data (profile in
Cartesian coordinates of the measuring area).
· RAW profile - transfer of uncalibrated data (profile in the
coordinate system of the CMOS sensor). Obtaining a profile in
this format allows you to visually match the profile and the
image formed by the CMOS sensor. This format is used for
debugging.

21.1. Time cycle
Image capture, processing (profile extraction) and result transfer are performed in a
pipeline mode. The pipeline mode is illustrated by diagram:
Description of elements is shown below:
Т
Frame (profile) period.
FPS
Frame (profile) rate.
N-1, N...
Frame (profile) numbers.
Event
Event that triggers the measurement cycle of obtaining a single frame (profile).
Exposure time
Exposure time of the image sensor.
Laser ON time
Time during which the laser is turned on.
Profile extraction and
transfer
Time required to extract the profile and start its transfer.
The measuring cycle (start of measurement to take one profile) always begins with
an event, the sources of which are described in the next paragraph. Upon the occurrence of
the event, the electronic shutter is opened and the laser is turned on, i.e. the CMOS sensor
is exposed. Simultaneously, the previous frame is read, processed (profile is extracted from
image) and transmitted.
