Abstract: Systems and methods for optical imaging using an optical sensor in an active area of the display are described. The optical sensor includes a set of detector elements positioned in a detector plane; a transparent layer; and a set of first reflective surfaces in the transparent layer. Each reflective surface in the first set of reflective surfaces is positioned to receive light from a portion of a sensing region of the display and to reflect the received light. The optical sensor further includes a second set of reflective surfaces, each reflective surface in the second set of reflective surfaces is positioned to receive the transmitted light from the first set of reflective surfaces, and to further reflect the received light towards one of the set of detector elements.

Abstract: An input device includes a transparent layer having a top surface and a bottom surface, and an inner layer positioned below and directly contacting the bottom surface of the transparent layer, wherein the inner layer has a second index of refraction (n2) that is lower than a first index of refraction (n1) of the transparent layer, and wherein a first region of the transparent layer extends past an end of the inner layer. The device also includes a light source positioned below the bottom surface of the transparent layer, and a reflector arrangement configured to reflect light emitted by the light source into the transparent layer in or proximal to the first region of the transparent layer, wherein at least a portion of the light reflected into the transparent layer propagates within the transparent layer by total internal reflection.
