FIELD: measuring equipment.
SUBSTANCE: laser phased range finder has transmitting system and receiving system. Transmitting system consists of scala generator, radiation source in form of laser, laser radiation collimator, rotary mirror and rotary prism. Receiving system consists of receiving lens, photodetector in form of avalanche photodiode, bandpass filter, controlled amplifier, heterodyne oscillator, mixer, high-voltage source, adder, microcontroller and temperature sensor. Receiving lens is made with central opening, in which rotary reflecting prism is installed, which reflecting face is located at angle of 45° to lens optical axis.
EFFECT: increasing of maximum measured range and reduction of measurement error due to improving signal/noise ratio.
