1.2 Interface parts
The mechanical interface of the LRF module base plate is defined by:
a three point mounting base with three threaded holes.
two positioning holes.
The electronic interface of the LRF module is defined by one system connector for power supply and
communication.
2 LRF Background Information
2.1 Rangefinder Principle “Pulsed LRF”
When the laser rangefinder is activated, a series of
laser pulses from the transmitter are sent through the
objective lens to the target. For a good result, most of
the laser pulses have to hit the target.
The main part of the laser light is absorbed or diffusely
reflected by the target and only very small percentage
of the light is reflected back to the LRF module. This
remaining laser light is received by the opposite
objective lens and focused on the receiver diode. The receiver diode (detector) starts sampling the echo
at a very high frequency.
Figure 3 below indicates how laser pulses are emitted from the transmitter, reflected at the target and
sampled by the receiver.
Figure 3: Pulsed LRF – Laser Pulses
The following Figure 4 illustrates the sampled signal of the receiver diode. This information is used to
calculate the distance.
Figure 4: Pulsed Diode – sampled signal at the receiver diode
Measurement Example:
Measurement time (return flight) = 6.66 µs
Time of flight (one way) = 6.66 µs / 2 = 3.33 µs
Slope Distance r = light speed x time of flight
= 300’000 km/sec x 3.33 µs ≅ 1000 m

2.2 Electronics
Safran Vectronix AG range finding technology is based on fiber lasers in combination with a multi-pulse
measurement system. This allows pulses with low energy compared to a single high energy pulse.
2.3 Ranging Conditions
In general two kinds of ranging conditions are described:
Range capability: The possible laser range performance on a beam filling target.
Range performance: The guaranteed range performance on a defined target under defined
conditions.
The range performance depends on visibility, target size and albedo (reflectivity) and is calculated relating
to a certain detection probability e.g. 90%.
Visibility
Visibility is the greatest distance from an observer where a prominent dark object against the sky on the
horizon can be seen and identified by an unaided eye. Good visibility allows the measuring of longer
ranges. Fog, snow, dust, sand, smog and rain reduce the visibility and therefore the range performance of
the LRF module.
Sunlight
Bright backlight or high sunlight reflections on the target can reduce the range performance.
Object Size
A typical target size for range performance comparison is the NATO target with a similar size to the front
of a tank. The size of a NATO target is 2.3x2.3 m. Additionally, the LRF performance is defined on a man
size target with a size of 1x1 m.
Small targets reflect only a part of the laser beam and therefore only allow lower range performance.
A large target allows longer ranges because more of the laser light is returned to the LRF module.
Figure 5: Example of a 0.5 mrad laser beam size on target
Object Albedo
The albedo is the surface's reflectivity of an object, or rather is the ratio of reflected to incident light in the
wavelength of the LRF Module (1550 nm).
An object with a high albedo reflects more laser radiation and allows longer range performance. High
albedos on very short distances and low albedos on very long distances can either cause the LRF
module to provide an invalid range measurement or to be unable to find a target.
Object Orientation
The angle of the target in relation to the laser beam is also important. Similarly, targets with a very high
albedo can give only a very small reflection towards the LRF module when the reflected laser radiation is
not at 90° and reflected away, e.g. on water or pitched roofs.
90° is optimal.
Object Hardness
The accuracy of “soft objects” like snow, smoke, clouds etc. depends on the condition of the object itself.
Hard objects allow a longer range and higher accuracy.

Page: 13/72
Mirror-like objects
The accuracy and range performance on mirror-like objects such as water, glass surfaces or reflective
traffic signs can cause incorrect measurements or no measurement results at all.
NOTICE
Avoid mirror-like surfaces and aim at a target next to it. It can cause incorrect measurements.
Kinetic tremor
If the host system with an integrated LRF module is firmly installed or mounted (e.g. on a Tripod), longer
distances can be measured more easily. If the LRF module is shaking during a measurement, it can lead
to wrong or no measurement results. This is due to the fact that only a few pulses hit the target during the
measurement. The example below shows a laser beam with 0.5 mrad divergence on targets in 2 km
distance. The range measurement on the large NATO target is still OK, but on the man size target it is
lost.
Firmly mounted modules allow a longer range, e.g. on tripod.

3.2 First steps with the LRF 7047
We recommend using an Interface Kit (Article Number 914752) to run a LRF 7047 with a PC. In this kit a
USB-power supply cable and an interface cable with a Samtec Connector are included. These two cables
have to be joined together via the blue Dubox connectors. The Samtec connector has to be plugged into
the Samtec System connector of the LRF. The USB connector is connected to a USB port of the PC. To
run the LRF 7047, power (8-42 V) has to be provided via the red (+ pole) and black (- pole) pin plugs. The
pointer interlock switch is protected by the red cap. To arm the pointer lift the red protective cover and
flick switch on (see figure 10 and figure 11).

LRF modules can be connected to your PC without an interface cable provided by Safran Vectronix. In
this case we recommend reading this manual carefully before using the LRF module. Please be aware of
the risk of wrong pin-connection or destroying the module by applying overvoltage and other errors.
For the correct pin configuration see chapter 5.1 System Connector and Signal Description.
Power supply must not exceed the operational range, see chapter 5.3 Operating conditions.
The common Interface settings present in most commercial applications, are listed below. Some of them may
not be necessarily present:
o Communication type: Serial
o Encoding (transmit and receive): ASCII UTF-8
o Speed: 57’600 baud rate
o Transmit delay inter-character: 0 msec
o Transmit delay inter-line: 0 msec
o Data: 8 bit
o Parity: even
o Stop bits: 1 bit
o Flow control: none
o Echo: On
NOTICE
Ensure the correct Communication Port is selected.
NOTICE
Some commercial interfaces send automatically the Carriage Return
Commercial software may use different nomenclature for Carriage Return ->
“<CR>” “\r” “<0D>
First range measurements can be performed by sending the software commands >LM,Md,3*D5<CR> to
the LRF module. To achieve a valid range result, aim at targets of at least 40 m distance and ensure that
you hit the target and that no obstacles such as closed windows are between the LRF and the target.
