  • Patent number: 5574275
    Abstract: An optical sensor and a method of operating an optical sensor. The optical sensor includes a plurality of unit cells, a plurality of groups of optical detectors, an amplifier and a plurality of selection circuits. Each of the unit cells includes at least first and second pixels, and each group of optical detectors is associated with a respective one of the unit cells. Each group of detectors includes at least first and second detectors to generate first and second electric signals representing the intensity of light incident on, respectively, the first and second pixels of the associated unit cell. Each of the selection circuits is associated with a respective one of the groups of detectors for transmitting to the amplifier the electric signals from the associated group of detectors.

  • Patent number: 5563406
    Abstract: An optical sensor and a method of operating an optical sensor. The sensor comprises a multitude of pixels, a multitude of optical detectors, an amplifier and a switching circuit. Each of the pixels includes an optical detector for generating an electric signal representing the intensity of light incident on the pixel. The switching circuit is electrically connected in series between the amplifier and the optical detectors for conducting the electric signals from the optical detectors to the amplifier in a predetermined manner. Preferably, the switching circuit includes a multitude of switches, and each switch is used to control the transmission of the signal from a respective one of the optical detectors to the amplifier.
