Abstract: A grid lateral photodetector having integral gain capability making possible the amplification of generated photocurrents prior to entry of the information in the position determining portion of the detector thereby significantly improving the operating characteristics of the detector especially at low noise levels. The subject photodetector includes a wafer element having an array of phototransistors with a common collector formed by a uniformly diffused semi-conductor region, and an array of diffused semi-conductor material connected to nodal points in a grid resistor array.

Abstract: A semi-conductor radiation sensitive transducer capable of producing an electrical output signal which varies with the centroid position of radiation including non-uniform radiation incident on a surface thereof, the subject transducer includes means capable of absorbing light radiations impinging thereon and producing charge carrier pairs which are separated in a transducer region of a high electric field such as in the depletion region of a Schottky barrier or p-n junction, the majority of the carrier current resulting from the absorption being divided and distributed to an array or grid structure formed by multiple discrete ohmic contacts connected by a network of resistive elements and to associated collecting electrodes said collecting electrodes being operatively connected to signal processing circuitry.
