Abstract
Image sensor with memory and, more especially, image sensor with reading by thermal effect. This sensor comprises mainly a layer of a photoconductive material and a layer of a transparent material, the impedance of which varies with the temperature, these two layers being comprised between two electrodes. Furthermore, a voltage generator can be connected to the electrodes during the recording when the device is illuminated. Finally, a charge amplifier can be used to detect a current when the unit is heated.
