Stereoscopic infrared imager having a time-shared detector array

摘要

A stereoscopic infrared imager includes optics for producing infrared images of two different views of an infrared scene. A scanning mirror alternately scans the two infrared images across a single infrared detector array. The detector array modulates a light source array to produce a visible image of the scanned part of the infrared scene. Optics are provided for producing visible images of the light source array at the positions of the eyes of the observer. A second scanning mirror alternately scans the image of the light source array across the two eyes of the observer in order to construct full visible images of the scene.
