Abstract: A film type light receiving element and a method for producing such an element in which the electric current ratio for light and dark input intensities is large while the resistance of an optically transmissive electrode is made low. Belt-shaped metal electrodes and a photoconductive film are provided on a smooth surface of an insulating substrate.

When a potential is developed across the electrodes 4, 8 and an X-ray pattern is projected through electrode 8 and into the liquid 7, the emitted ions of one polarity migrate to the mirror film 6, and cause the elastomer layer 5, and the mirror film 6 along with it, to deform in a pattern corresponding to the X-ray pattern. Such deformation may be optically projected for readout by a Schlieren system or the like.
