PHOTO-DETECTOR AND METHOD FOR DETECTING AN OPTICAL RADIATION

摘要

A system for the acquisition of an image is described. The system comprises a photo-detector of a radiation, the photo-detector implementing at least one tunable spectral response indicating the sensitivity of the photo-detector as a function of the wavelength. The photo-detector includes means for receiving at least one configuration signal controlling the tuning of at least part of the shape of the at least one spectral response. The system further comprises a control module for receiving an identification signal indicating the spectral intensity of a source of light, for detecting that the shape of the source spectral intensity in at least one spectrum portion is different from the shape of a reference spectral intensity in the at least one spectrum portion, and for changing the at least one configuration signal in order to change the shape of the at least one spectral response in the at least one spectrum portion as a function of the difference between the shape of the source spectral intensity and the shape of the reference spectral intensity in the at least one spectrum portion.
