Improvement of Laser Rangefinders with Pulse Energy Safe for Human Eyes

Аннотация

The characteristics of a laser rangefinder with a wavelength of 1.54 μm having a radiation pulse energy less than the threshold value safe for human eyes are calculated. Two examples of photodetectors with increased sensitivity are given. A system for pumping the laser active element by laser diode lines is proposed which increases the efficiency of the laser emitter and decreases the energy load on the active element.
