Abstract

Optical system having application to robotics for determining an object's position. The present system consisting of a laser generator 1 with, devices 11 modulating the wavelength of laser generator frequency along an ascending ramp. An optical system 8 for concentrating radiation near the object, receiver 16 picks up a luminous signal transmitted by the object 10 and reflected on to an optical lamp 6. A processing circuit 17 measures the time in which elapses between the beginning of the shift in wavelength and the moment when the luminous signal is picked up by the receiver.
