Electronic imaging apparatus with high resolution and wide field of view and method

摘要

Electronic imaging apparatus includes a main mirror that rotates about two transverse axes to reflect light for an array of subimages through a lens to a correcting mirror that reflects the light to an image detector. The correcting mirror moves in translation and tilts to correct for loss of focus of the subimages. A method of generating high resolution images includes acquiring an array of subimages by moving the main mirror and correcting each subimage with the correcting mirror. A method of surveillance includes acquiring and storing an array of initial subimages, then acquiring new subimages, comparing the new subimages with the stored subimages, and storing changed subimages.
