Military Laser Rangefinder Category

Military optoelectronic system is the core of optoelectronic devices (mainly lasers and photodetectors), the integration of optical technology, electronics / microelectronics and precision mechanical technology, etc., with specific tactical functions of military equipment.In terms of the classification of military optoelectronic systems, there are usually two classification systems: one is based on its configuration and mode of delivery of the “piggyback” classification system; the other is based on its tactical functional attributes of the “functional” classification system.

According to the functional classification system, military optoelectronic systems can be divided into eight categories: early warning and remote sensing systems, reconnaissance and surveillance systems, fire control and targeting systems, precision guidance systems, navigation and guidance systems, range measurement systems, optical communication systems and optoelectronic countermeasure systems, etc. ERDI mainly introduces the category of military laser rangefinder.
