LASER RANGE FINDER Russian patent published in 2018 - IPC G01C3/08 

FIELD: laser engineering.

SUBSTANCE: invention relates to laser technology, namely to the equipment of laser ranging. Laser rangefinder contains a laser semiconductor emitter with a pump current sensor, two-channel receiver with switch input, at the output of which the distance calculator is switched on, the receiving device consisting of a photodetector connected to the first input of a two-channel amplifier, second input of which is connected to the current sensor of the laser emitter, second two-channel receiver with a switch input, output of which includes a distance calculator. Receiving device consists of a photodetector connected to the first input of a two-channel amplifier, second input of which is connected to the current sensor of the laser emitter, and also a splitter of the output radiation of a laser semiconductor emitter, first beam of output radiation directed to the first object, located in the field of view of the first receiver, and the second beam - on the second object, which is in the field of view of the second receiver, in this case, a differential distance calculator is introduced to the first and second objects.

EFFECT: technical result is an increase in the accuracy of the laser rangefinder.
