Detector array structure for eliminating channel spectrum

A detector array that eliminates the channel spectrum effect. In one embodiment the detector consists of a charge couple device (CCD) detector having a photoactive layer supported on a wedge-shaped substrate. Incident radiation impinging any of the pixels and passing through the substrate to the wedge-shaped surface thereof is reflected back at an angle away from the pixel from which it passed through. An infrared array and a single element detector each including a wedge-shaped substrate are also disclosed. The detectors do not require costly signal processing equipment and further can be constructed in accordance with well known manufacturing techniques and with little or no additional cost beyond that normally associated with producing such devices.
