Abstract
The invention relates to an apparatus for optical image recognition and classification, comprising an optical setup () to split the optical image into n=1, 2, N local optical power values P, a detector array () with n=1, 2, . . . N photoactive pixels (″) to pick up the local optical power values P, wherein each pixel (″) is segmented into m=1, 2, . . . M subpixels (), and each subpixel () comprises a semiconductor photodiode which, under optical illumination, delivers a photocurrent Idepending on its photoresponsivity Rand the local optical power Preceived at the pixel (″), and wherein the photoresponsivity values Rare not identical, and the outputs of each subpixel () are connected to form M output lines (), wherein each output line () sums the photodetector currents produced by the m-th subpixels () in all N pixels (″) and delivers a detector current of Formel (I), to be used for recognizing and classifying the optical image.
