Laser systems

Lasers have found a very wide area of applications and laser systems are offered in thousands of different types. Inframet manufactures equipment for testing several types of laser systems that support EO imaging systems by distance measurement  or use an  imaging system for precision aiming.

In detail, Inframet offers equipment for testing four group of laser systems:

  1. Laser range finders,
  2. Laser pointers/illuminators/dazzlers,
  3. Laser receivers (laser communication receivers, laser seekers, laser trackers),
  4. Thermal infrared lasers.

Laser range finder LRF is a measuring  device  that uses a laser beam to measure the distance to a target; typically using  time of flight principle. Laser pointer/illuminator/dazzler  is a device that uses laser beam to indicate/illuminate/or dazzle target of interest. Laser receivers are devices that work as receiver blocks of laser seekers,  laser communication systems or laser trackers having a task to detect a target emitting pulsed laser light.  Thermal infrared lasers are lasers operating in long wavelength spectral range (thermal infrared) from about 2 μm to 15 μm.

Inframet offers a long series of stations for testing earlier listed laser systems:
a)Laser ranger finders: LTE ,LUNI,  LTF, LAS,  LJT120 , LATRA, LIS, LMOB, LBOR,
b) Laser pointers/illuminators/dazlers: LIP,
c) Laser receivers: L64,
d) Thermal infrared lasers: LTIR.

LIP test station LTIR test station

 Table 1. Basic descriptions of offered stations for testing laser systems
Code Basic description Test capabilities
LTE Semi-automatic station for expanded  testing  of laser range finders. Mature design offered from about 2010. Pulse energy, pulse width,pulse frequency, beam divergence, receiver sensitivity, distance accuracy, Extinction Ratio,max operational range boresight errors
LUNI Universal  station for expanded  testing  of laser range finders. New  design offered from 2020. Pulse energy, pulse width, pulse frequency, beam divergence, receiver sensitivity, distance accuracy, Extinction Ratio,max operational range boresight errors
LTF Simple reliable station for final quality control Extinction Ratio, distance accuracy, max operational distance, distance discrimination (option), checking boresight
LAS System to enable measurement of operational range or ER extinction ratio of LRFs at field conditions  Operational range, extinction ratio ER, support for recalibration of laboratory stations
LJT 120

Excellent tool  for fast easy boresight  of LRFs for  manufacturers, integrators or repair workshops

 boresight transmitter/ receiver/ aiming channel
LATRA

Moderate cost station that offers the same boresight capabilities as LJT120 at slightly  lower test speed

 boresight transmitter/ receiver/ aiming channel
LIS LIS station can be considered as a highly simplified version of LTE station. The station is optimized to test
a specific type of LRF but its buyer can define parameters of LRF to be tested. 
LMOB

Variable distance simulator for testing receivers electronics of laser range finders

 Distance measurement accuracy
LBOR

Portable boresight tester of transmitters of laser range finders to be aligned with optical sights or VIS-NIR video cameras

 Boresight errors
L64 Station for testing laser receivers (including laser seekers) and laser trackers Checking reactions  to a simulated pulsed laser source of regulated properties
LIP Advanced station for testing  laser pointers/illuminators/dazzlers Power, divergence angle,uniformity  of laser pointers/illuminators
LTIR Professional system  for testing and boresight of thermal  infrared lasers. Ultra accurate measurement of divergence angle,  temporal and spatial stability
