Abstract
A detector surface which is based on optical signals and arranged as a flexible enveloping surface around the body in order to detect whether and where the illuminated indicator strikes the body. The detector surface composed of one or more planar optical fibers, wherein at least one layer of a planar optical fiber has photoluminescent properties, and wherein photodetectors are arranged on the planar optical fiber such that they can decouple light from the optical fiber and detect it. The planar optical fiber is designed as a film made of a transparent polymer having a thickness of 30 to 500 μm and the photodetector is arranged at a distance from all edges of the optical fiber on the optical fiber.
Claims12
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.
