2. DESCRIPTION

The LRF is manufactured from a precision machined aluminium chassis with O-ring sealed outer case optimised for stable operation over the wide temperature range experienced in homeland security and other demanding applications.
A laser diode and associated optical system generates a sequence of laser pulses which are transmitted to the object being measured. The reflected pulses are detected by the receiving optical system which focuses the light onto a high performance InGaAs detector. The detector output is amplified, digitised and then processed using a novel DSP algorithms to calculate the distance to the object.
For any LRF, there is a trade off between the signal to noise ratio of the received signal; precision of the range measurement; maximum range; and energy and time required to make the measurement. The patented digital signal processing based technology allows the trade-off between these factors to be optimised. As standard the LRF operates in an autonomous mode, adapting the measurement time to the strength of the returned signal and using the signal to noise ratio to optimum effect so that for objects at shorter ranges, the measurement precision is enhanced. Alternative trade-offs can be provided to suit different applications and we would be pleased to discuss these.

3. OPTIONS
The following options are available or planned.

3.1 Chassis Version

For those customer’s wishing to integrate the LRF200 Series within their own housing, the LRF200 Series can be supplied in an open frame configuration without the rear case or rear connector.

 

3.2 Vehicle Power Supply Filtering

To allow the LRF200 Series to be powered directly from a vehicle supply, an additional filter can be integrated into the case, to protect the LRF against the transients and surges normally experienced with such a supply. The filter is MIL-1275 compatible.

 

3.3 Vehicle Ruggedisation

The LRF200 Series in its basic form is compact and rugged unit. However, for those applications where sustained, high levels of shock and vibration are expected a ruggedisation option is available in which the larger components such as capacitors and inductors are glued or tied to the printed circuit board. This option is relevant for applications such as off-road surveillance vehicles and police or customs helicopters.

 

3.4 Integrated CCD Camera/Graticule Generator
The LRF200 Series is available with an integrated CCD camera, which views the scene via the LRF receiver lens and optical channel which incorporates a beam splitter to allow the LRF detector and CCD camera to operate simultaneously.
The CCD camera can either be used as a narrow field of view camera for scene observation or, in conjunction with the optional graticule generator, to allow boresighting of the LRF with other sensors: for example, night vision cameras. The CCD camera continues to operate whilst the LRF is firing, without disruption of the video signal. This is particularly useful when a video auto-tracker is used to keep the LRF line of sight aligned on moving objects, or where the video is being recorded for evidential purposes.
So far, we have supplied the LRF with a monochrome camera, but would be able to supply colour if required.
Please contact the factory for more details.

3.5 RS422 control interface
As an alternative to the standard RS232 control interface, we can supply the LRF with an RS422 interface for greater noise immunity.

3.6 Starter Kit

To allow customers to get the LRF up and running quickly, we offer a starter kit comprising Windows XPTM compatible control software, a power/data cable and a universal mains power supply module. The software allows the operator to set the minimum and maximum range gates; fire the LRF; display the first and last range measurements and put the unit into standby and sleep modes.

3.7 Weaver Rail and Telescope Kits

A Weaver rail kit can be fitted to the top of the LRF case to allow additional optical instruments to be attached to the LRF. An optional 6X optical sight is offered as an option to fit to the Weaver rail. The photograph to the left shows the Weaver rail and telescope fitted to the LRF.

4. OUTLINE TECHNICAL SPECIFICATION

The above figures are provision ratings and assume typical applications. Actual performance will depend on many parameters including configuration and environmental conditions

5. LASER SAFETY
Laser safety guidelines documents are available on request.

6. INTERFACES

6.1 Mechanical interface
Please refer to the outline drawing.

6.2 Communication interface
The LRF module is controlled by means of a serial communications link complying with TIA/EIA RS-232.
Please refer to Communications protocol document available on request.

6.3 Electrical interface- Chassis version
The unit is fitted with a MOLEX 87831-1620 16 way PCB mounted connector which is designed to mate with a cable mounted MOLEX 51110-1651 16 way connector.
