Abstract: In an acoustoelectric converter element, a light wave from a light source is introduced into a first optical waveguide of a vibration substrate, and diffracted by a diffraction grating disposed on the first optical waveguide. The diffracted light is directed to and detected by a photo detector. Here, the vibration substrate is so supported as to vibrate with respect to an acoustic wave. Therefore, the diffracted light detected by the photo detector is modulated by the acoustic wave, and a signal is output from the detector in accordance with the acoustic wave.

Abstract: A device for performing identification by sensing the fingerprint of a finger includes an input unit. The input unit is constituted by a plurality of linear contact electrodes formed on a substrate, and a pressure-sensitive sheet formed on the linear contact electrodes and a resistance thereof changes in accordance with a pressure applied thereto. When the finger touches the surface of the pressure-sensitive sheet, a change in resistance is caused between the electrodes, and this change is converted to data of a one-dimensional electrical signal distribution. The obtained data is compared with registered data, thereby performing identification. The time required for signal processing necessary in the identification device can be decreased.

Abstract: A solid state radiation detector has semiconductor layers and metal layers which are stacked along the incident direction of radiation rays. Each metal layer is made of a specific metal material which receives radiation rays entering itself and produces free photoelectrons by interactions therewith. The photoelectrons are introduced into the semiconductor layer, and excite it, thereby producing electron-hole pairs therein. The metal layers serve not only as radiation detecting layers but also as electrodes for collecting the electron-hole pairs. Therefore, when the produced electron-hole pairs are derived from the metal layers, an electrical radiation detecting signal may be produced.
