Abstract:

A method of measuring distances based on the use of a light range meter with an active reflector working on fixed frequency is described. The phase delay in the active reflector is eliminated by control of the phase of the modulating voltage with respect to the light extremum visually observed during cophasal supply of the modulator and demodulator of the active reflector to increase the active range and broaden the possibility of observations during the daytime. The coherence of the oscillations of the modulating voltages of the base station and of the active reflector is ensured with the aid of a reference signal transmitted onto the active reflector along a radio channel from the generator of the modulating voltage of the base station.
