FIELD: physics.
SUBSTANCE: laser range-finder consists of radiation source, beam splitter, first optical delay line in the calibration channel, second optical delay line, in the measurement channel, first and second light shutters, placed in front of the first and second delay lines respectively, receiving optical system, made in form of an objective, light detector, timer, frequency meter, control channel for the radiation source, which has an inverter and control and power supply unit, and a data processing unit.
EFFECT: wider dynamic range of the laser range-finder with retention of high accuracy of measurements.
