ABSTRACT:
A totally integrated imaging system has a housing including imaging optics, a scanning mirror and a curved detector array. The imaging optics constitute a meniscus lens and a spherical focusing mirror. The scanning mirror scans the image, and the spherical mirror focuses the scanned image onto the detector array. The meniscus lens advantageously corrects aberrations. A detector support provides access, if desired, for cryogenic cooling of the detector, and individual cold shielding of the detector elements is made possible by the telecentricity of the optics. Processing electronics, at least a portion of which may also be disposed on the detector support, process the detector signals to display an image. The integrated structure advantageously eliminates any need for separate scanner, imager, and electronics modules and the scanning optical system obtains highly desirable image quality over a wide field of view.
