Abstract
Disclosed are systems and methods for imaging an object. For example, an optical sensor for imaging an input object, comprises: a sensor substrate comprising detector pixels; a scattering layer; a cover layer including a sensing surface, wherein the scattering layer is disposed between the sensor substrate and the cover layer; and, a light source. The optical sensor is configured to: illuminate the light source causing light beams to emanate from the light source to produce an effect of a point light source at the scattering layer; and acquire image data, from one or more detector pixels, of an input object in contact with the sensing surface, wherein the image data corresponds to light from the light source that is reflected at the sensing surface of the cover layer.
