摘要
FIELD: physics.;SUBSTANCE: method is based on determining from the measured value of the time interval between instants when one body detects the other at long and short distances, by detecting one body using the other by probing space with light pulses and detecting reflected radiation followed by analysis. Probing light pulses are emitted by one emitter and the reflected radiation is detected by one receiver mounted on one of the bodies; an established series of light pulses is emitted during a given time interval; the signal indicating detection of a body is generated upon detection of reflected signals of all emitted light pulses of the current series and upon detecting a finite reflected signal of the series in a test time window.;EFFECT: high accuracy of determining the approach speed of two bodies with protection from small-size interference, minimisation of size and weight characteristics and power consumption of the device.;2 cl, 1 dwg
