摘要： A voltage is electrostatically induced at a sensing device (ED) in correspondence with a surface potential of a measured object (O). In the case where the sensing device uses a field effect transistor (DF) in transferring detected information, there are some factors decreasing the accuracy of detection. Various new arrangements prevent such decreases in the accuracy of detection. In the case of the surface potential of the measured object corresponds to an optical image, new arrangements ensure accurate detection of the optical image. In some cases, color component signals are obtained on the basis of a detection signal.

摘要： There is disclosed a recording/reproducing system comprising an optical system for directing along a path of an electromagnetic radio ray from an object toward a recording medium, and a recording head disposed in the path for generating a charge latent image onto the medium. The feature of the system resides in that the recording head (system) forms the detection region which is not entirely subject to the influence of the electromagnetic radio ray and which is provided in a portion of the charge recording region of the medium, and in that a reproducing system discriminates the polarity of charges or the recording mode of the charge latent image recorded onto the medium by detecting the charges in the detection region.

摘要： A reproducing apparatus which reproduces a charge latent image recorded in a recording medium. The apparatus has an electromagnetic radiation source, an optical system for leading an electromagnetic radiation ray emitted from the electromagnetic radiation source in a direction toward a recording medium on which an object information to be read is prerecorded as a charge latent image, and a read head arranged closely facing to the recording medium and arranged in series in a travelling path of the electromagnetic radiation ray. The read head is of a multilayer structure comprising a support base plate, a photo modulation material layer for generating a mode modulation of said electromagnetic radiation ray which passes the photo modulation material layer therethrough in response to intensity of an electric field by said charge latent image, and an electrode for applying a predetermined electric field to said photo modulation layer, and for allowing to receive the electromagnetic radiation ray in a read wavelength range and transmit thereof to the photo modulation layer, an output surface facing to a processor for emitting thereto the electromagnetic ray having passed through the electrode and the photo modulation layer, said processor processing the electromagnetic ray modulated by going through the photo modulation material layer and outputted from the output surface.
