Description

technical field [0001] The invention belongs to the field of target detection and identification and information transmission, in particular to an integrated system of laser ranging, polarization imaging and laser communication. Background technique [0002] Laser ranging technology is a technology that uses laser to accurately measure the distance of the target. It is the earliest and most widely used technology of laser in military applications. According to the classification of laser ranging methods, it can be divided into two types of technologies: pulse laser ranging and continuous wave laser ranging. Pulse laser ranging is to use a pulse laser to emit one or a series of very narrow light pulses (pulse width less than 50ns) to the target, measure the time for the light pulse to reach the target and return from the target to the receiver, and calculate the distance of the target. The pulse laser rangefinder has high transmission power, strong ranging capability, and sm...
