Type classification and application analysis of pulsed laser range finder
As a military equipment, the pulsed laser rangefinder was developed in the early 1960s. After more than 30 years of development, development and equipment, foreign countries have completed "handheld, tripod, periscope, tank, armor, surface carrier, submarine periscope, antiaircraft gun, airborne, airport cloud, missile There are more than 400 varieties and models in thirteen categories, including rocket launch, artificial satellite, and spacecraft, among which the solid-state pulse laser rangefinder with Nd:YAG as the device is the most equipped, followed by Raman frequency shift Nd:YAG and Er:glass and CO2 pulsed laser rangefinders.
Lightweight Portable Pulsed Laser Rangefinder
Lightweight portable pulsed laser rangefinders include handhelds for infantry and artillery reconnaissance and dual-purpose forward reconnaissance and forward air control (FAC) laser rangefinders-target designators. For the above-mentioned system, it is required to be flexible, light in repetition, small in size, use a battery pack as a power source, high in reliability and maintainability, and low in cost of a single product.
Main technical performance: the maximum measurement range is 4~10km, the distance measurement accuracy is ±10m, the repetition frequency is single, and the beam divergence angle is 1~2mrad. It is worth noting that since the above-mentioned laser range finder and its system often cooperate closely with other friendly forces and do not carry out large-scale training of armored forces, there are no cooperative targets, and the operator does not wear protective goggles, etc., human eye safety is extremely important. Therefore, this type of pulsed laser range finder has gradually changed from Nd: YAG laser range finder to Raman frequency shifted Nd: YAG and Er: glass 1.54μm eye-safe laser range finder.
