ABSTRACT:
In an optical sensor, a heating element is formed on a substrate, and an amorphous semiconductor film is formed on an insulating layer covering the heating element, and is electrically insulated from the heating element. A common electrode and a plurality of electrodes are also formed on the substrate and are extended along the amorphous semiconductor film, to form cells for converting light into electrical signals, in the amorphous semiconductor film. An electric current is supplied to the heating element, to heat the amorphous semiconductor film after the film has been illuminated and photoelectric current has been picked up from the electrodes.
