PHOTOSENSITIVE DEVICE AND METHOD FOR CONTROLLING SAME

摘要

The invention concerns a photosensitive device comprising a matrix of photosensitive points particularly of the type produced by semiconductor material deposition techniques. More particularly (but not exclusively), the invention concerns the control of such devices used for detecting radiological images. The invention also concerns a method for controlling the photosensitive device. The photosensitive device comprises means for adjusting the polarisation amplitude for separately adjusting the polarisation amplitude of the photosensitive points (P1 to P9; P401 to P 409). The method for controlling the photosensitive device comprises a calibration phase which consists in adjusting the polarisation amplitude of each of the photodetector elements (Dp) independently of one another, so as to obtain the best coincidence of the output saturation levels between two photosensitive points.
