Abstract

Described are handheld devices with combined image capture and image projection functions. One embodiment includes modulating and capturing a light beam along the same optic path. In another embodiment, the optical components are operable to switch between projection and capture modes. In yet another embodiment, the optical components may be formed on the same semiconductor substrate thereby increasing functionality.
