A channel for measurement of vehicle rate with multichannel longitudinal mode selector for laser information and measuring systems of a range test complex comprises a control element, block for control of deflectors, pumped laser, multichannel longitudinal mode selector, block of deflectors, transmitting optics, receiving optics, photodetector, broadband amplifier, information block, resonance amplifiers adjusted to respective frequencies of inter-mode beats, pulse formers, triggers"1"|0", circuits AND, reversible counters, comparison circuits (CC) and &Dgr;v– input of reference signals with frequencies of inter-mode beats (&Dgr;v, 2&Dgr;v, 3 &Dgr;v, 6&Dgr;v) from transmitting laser, differing by the fact that after CC instead of electronic-digital computing machine an electronic computer is included. |
