Systems and methods for optical imaging are disclosed. The systems and methods include a display for imaging an input object. The display includes a sensing surface; a plurality of display pixels; a plurality of detector pixels; and a processing system. The processing system is configured to determine a location of the input object relative to the sensing surface; illuminate one or more display pixels of the plurality of display pixels according to a pattern depending on the location of the input object; and acquire image data of the input object from one or more detector pixels of the plurality of detector pixels, wherein the image data corresponds to light from the one or more display pixels that is reflected at the sensing surface.
