FIELD: physics.SUBSTANCE: method is based on detecting an object using pulsed optical radiation and detecting the reflected radiation, followed by analysis. Distance between bodies is determined using one emitter and one receiver mounted on the same body. An established series of light pulses is emitted over a given time interval and the distance between bodies is determined if reflected signals corresponding to all emitted light pulses of the current series are detected and upon detection of the final reflected signal of the series in a test time window, the location of which determines the distance between bodies and its duration determines the error in determining distance. The time of emitting each subsequent pulse is calculated based on the preceding time delays, which are defined as time intervals from the moment of emitting each pulse to the moment of detecting the corresponding reflected signal.EFFECT: possibility of minimising size and weight characteristics of the device and power consumption thereof, high accuracy of determining distance between bodies with the possibility of protection from small-size interference.2 cl, 1 dwg |
