OPTICAL DEVICE FOR DETERMINING DISTANCES TO OBJECT Russian patent published in 2017 - IPC G01S17/08 G01S17/10 

FIELD: physics.

SUBSTANCE: optical device for determining distances to the object includes a radiation source, a probe sequence generator, a clock generator, a light-sensitive element for detecting a reflected optical signal from the object, an integration unit, a correlation module for the radiated and reflected signals, a threshold signal detecting module, a distance detecting module to the object by the time delay of the reflected signal. In addition, the device includes an accumulation unit, a reference source of precise time and frequency signals, a sync pulse generation unit at the start of the sensing cycle at the same time point on different optical devices, a probe counting unit, a sampling and probe processing unit.

EFFECT: ensuring the mutual influence suppression of the optical device sounding signals to determine their distances to the probed objects in a group operating simultaneously on the same probed objects in the same frequency range of optical devices.
