Study to Testing Device of Pulse Laser Range Equipment

摘要

Electro-optical testing device is the important technical means to guarantee the operation efficiency of laser range equipment in complex battle environment. Several important indexes must be tested to ensure the good operation of pulse laser range equipment, such as the collimation of optical axes, the maximal measuring distance, laser emitting energy, resolution capability, and laser spot quality. A new kind of testing device is provided in paper. On the one hand, delay simulating space distance by computer and quasi-laser is used in the term of testing electrical parameters. The testing method is to collimate the emitted laser beam and disperse the beam into a photometric sphere. Then, emit with a regulated temporal delay a new beam into the receiver module of the laser range finder, which can realize automatic, fast and non-disassembly testing to electrical parameters. On the other hand, a new kind of infrared-detecting transforming device based on up-conversion effect is used in the term of testing laser spot characteristics, which can realize the capturing of laser spot in real-time to the pulse laser range finder and high-frequency pulse laser measuring range system. Applications show the testing device is automatically and quickly for many kinds of laser range finder, which has the characteristics of compact structure, portability, high reliability, which is especially suitable to the application under field operations.
