1. An electrical-output optical image sensor for a two-dimensional optical image composed of an arrayed plurality of contiguous two-dimensional optical sub-images bearing light energy, said sensor comprising: an image surface for receiving said two-dimensional optical image and transmitting a portion of the light energy of each said two-dimensional optical sub-image as a corresponding two-dimensional sub-image-bearing flux; an arrayed plurality of minifying means including two-dimensional minified sub-image surfaces and corresponding in number and arrangement to said plurality of contiguous two-dimensional optical sub-images, said minifying means receiving and transmitting each said two-dimensional sub-image-bearing flux in image-coherent geometrically reduced form as a corresponding two-dimensional minified sub-image-bearing flux incident upon and through a corresponding said two-dimensional minified sub-image surface; and arrayed flux-sensitive electrical-output image sensor modules, each having a flux-sensitive two-dimensional image-input surface in register with a corresponding two-dimensional minified sub-image surface and receiving a corresponding two-dimensional minified sub-image-bearing flux, and having electrical means for converting said two-dimensional minified sub-image-bearing flux into a corresponding pattern of electrical signals.
