Patent ID: 8410421

Claim:
A detector surface for optical signals which is constructed from one or a plurality of planar layers and which is arranged as a flexible enveloping surface around or on a body in order to detect whether and/or where a luminescence-generating light spot strikes the body, wherein the detector surface is constructed from one or a plurality of planar optical waveguides, wherein at least one layer of the planar optical waveguides has photoluminescent properties, and wherein a planar optical waveguide is connected to at least one photodetector via a light-transmissive contact surface, wherein the planar optical waveguide is formed as a film composed of a transparent polymer having a thickness of 20 to 500 μm, and in that at least one of the photodetectors is arranged on the optical waveguide at a distance from all edges of the optical waveguide in order to sense the photoluminescent light in the optical wave guide generated when the luminescence-generating light spot strikes the detector surface.
