OPTICAL DEVICE FOR DETERMINING DISTANCE TO OBJECT Russian patent published in 2016 - IPC G01S17/08 

FIELD: optics.

SUBSTANCE: device includes a radiation source of modulated binary optical signal, modulating generator in the form of a binary sequence of maximum length, a clock signal generator, light-sensitive detector signal reflected from the object, analogue-to-digital converter, a module for calculating correlation of emitted and reflected signals, a threshold signal detection, a module for calculating distance to the determined object at a time delay of the reflected signal. Device additionally includes an integration unit, a buffer memory, signal conjunction, a unit for generating multiple sync pulse of distance determination, unit for calculating the time delay for reflected signal, unit for converting zero signal in negative signal.

EFFECT: reduced power consumption of the device due to reduced load on computer modules.
