Non-Contact Array Readout

Innova Laboratories will develop an optical voltage measurement device for read-out of cryogenic infrared sensor arrays using a non-contact technique allowing data to be read-out by optically addressing a capacitive sensor. Because the read-out means does not contact the array, heat input to the array from conductive signal paths is minimized. Pixels are addressable randomly, allowing data to be read either serially or in parallel data streams. The technique offers ultimate read times than a microsecond and operation at a wide range of temperatures and frequencies. Commercial uses include: spectroscopic characterization of materials, high frequency radiation detectors, mixers, and logic elements in computers.
