Abstract

A combined Iight projection and detection apparatus comprising a Iight emitter (20) and a detector (40). The light emitter (20) preferably comprises a spherical, lensed body (24) containing a reflector (23). The Iight emitter receives Iight (7), preferably via a waveguide (60) from a Iight source (10) controlled by a processor (50), and projects the Iight (7) along a projection axis XP onto a target surface (2). The target surface (2) is observed by the detector (40), e.g. a camera, which preferably receives Iight (8) along the same projection axis XP. The projected Iight (7) may comprise a pattern or image which is modified by the processor (50) to provide a semantic lighting system, e.g. for playing virtual chess on a target surface. The Iight source (10) may comprise an array of Iight emitting elements (11), e.g. LEDs, which are individually adjusted to obtain an even radiant intensity over the target surface (2), e.g. for photodynamic therapy.
