A system for imaging a textured surface comprising includes a photoreceptor array having: at least a first photoreceptor and a second photoreceptor, each configured to receive electromagnetic radiation reflected from the textured surface and to generate a signal corresponding thereto; wherein the photoreceptor array is configured to detect an image of the textured surface based on the relative difference between the time of arrival of the signals from the first and second photoreceptors. Methods for imaging a textured surface and fabricating a photoreceptor array structure for imaging a textured surface are also provided.
