    摘要: A sensor device includes a sensor array in which infrared sensors are arrayed and a detection circuit connected to the output signal line of the sensor array. The detection circuit includes a capacitor having a charging circuit which is selectively driven, a sense amplifier circuit which detects and amplifies a change in sensor current flowing to the output signal line, a current-to-voltage conversion circuit which converts the output current from the sense amplifier circuit into a voltage, a discharging circuit which is controlled by the output voltage of the current-to-voltage conversion circuit to discharge the capacitor, and an output circuit which outputs the terminal voltage of the capacitor.

    摘要: 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.
