ABSTRACT:
An image conversion device (14) comprising a detector (38) for detecting an infrared image and an image converter (40) for converting the infrared image to a visible image. The detector (38) and the image converter (40) are disposed on a single substrate. The detector (38) includes an array of multiple quantum well detectors (38) formed of GaAs or GaAlAs. The image converter (40) includes an array of light emitting diodes formed of GaAsP deposited on the array of multiple quantum well detectors (38). A photoemissive surface (28) is formed on the array of light emitting diodes (40) and a phosphor screen (30) displays the visible image.
