Abstract
Optoelectronic detectors (10) are arranged in matrix form. Integrated synchronous detectors (22) are connected to each column of the detectors (10). The detection is modulated and the detection signals demodulated by the synchronous detectors (22) making it possible to considerably improve the signal/noise (S/N) ratio of the apparatus.
