The LT test system is a modular  measuring set that enables measurement of all important parameters of laser range finders and laser illuminators.

General concept of testing laser range finders is based on idea to collimate the emitted laser beam; disperse the beam; measure energetic, temporal and spatial parameters of the beam; and emit (with a regulated temporal delay) a new beam into the receiver module of the laser range finder.

Basically the LT test station is built from three main blocks: LT tester, PC (with frame grabber),  LAS software.

The LT test system enables measurement of the following parameters of laser range finders:

  1. pulse energy

  2. pulse width

  3. pulse frequency

  4. beam divergence

  5. receiver sensitivity

  6. accuracy of distance measurement (single target)

  7. accuracy of distance measurement (case of multiply reflections)

  8. bore-sighting  of the laser emitter (in reference to optical axis of an internal optical sight, or external visible imager/thermal imager)

  9. aligning of receiver (in reference to the emitter).  

Due to some new modern features (very wide pulse energy range, simulation of multiply reflections, ability to test high frequency laser range finders) the LT test station  significantly exceeds other commercially available test stations.
