摘要： There are provided an image information processing method and an apparatus thereof to process information carried by an electro-magnetic radiation beam by means of a photo-to-photo transducer. An intensity of an image information is adjusted by varying the intensity of an electro-magnetic radiation beam used for reading the information as electro-magnetic radiation beam information, which has been recorded on the transducer as a charge image. The electro-magnetic raidation beam information read out from the transducer is inverted by changing an operating range of a photo-modulation layer which is one of the components of the transducer. Furthermore, the electro-magnetic radiation beam information read out from the transducer is nonlinearly processed.

摘要： There is provided a photosensitive medium for recording a charge latent image, composed of a photo-conductive layer having an electrode and a protective layer at each surface thereof. There is further provided a charge latent image recording method. A photo-conductive layer and a charge holding layer, each having an electrode at a surface thereof, are arranged to face each other through a gap. A predetermined voltage is applied across the photo-conductive layer and the charge holding layer through the electrodes to cause discharge thereacross. At the time, an electro-magnetic wave corresponding to the charge latent image intended to be recorded is emitted to the photo-conductive layer. The impedance of the photo-conductive layer is thus varied to record the charge latent image on the charge holding layer. In the method, the rise time constant of the voltage applied across the electrodes is adjusted to that of the discharge or more, and the potential of the charge latent image is adjusted to a discharge starting voltage or less.

摘要： An electromagnetic radiation beam scanning system for scanning an object with an electromagnetic radiation beam. The scanning system comprises first and second beam-narrowing devices which are arranged so as to have elongated light-transmission regions, respectively, and which are overlapped each other so that the light-transmission regions intersect each other. Each of the beam-narrowing devices includes a light modulation layer showing an electro-optic effect, first and second electrodes disposed so as to sandwich the light modulation layer, first and second polarizers disposed so as to sandwich the light modulation layer and a power source for applying voltages to the first and second electrodes. The light modulation layer combined with the polarizers forms the elongated light-transmission region in response to application of the voltages to the first and second electrodes due to the power source so as to produce a narrowed beam when a light beam is incident thereon. The position of each of the light-transmission regions in each of the first and second beam-narrowing devices is arranged to be movable in response to variation of at least one of the application voltages due to the power source.
