摘要： A touch-sensing apparatus operates by transmitting light by total internal reflection (TIR) inside a planar light guide (1). A light projection system (10, 14) is arranged to define a grid of light propagation paths inside planar light guide (1) and generate a projection value for measurement light received on a respective light propagation path. A touch controller (24) is arranged to receive and process the projection values for determining a property (e.g. location) of objects on the planar light guide (1). The light projection system (10, 14) comprises a plurality of identical, unitary emitter-detector modules (10) that are disposed in optical contact with the planar light guide (1). Each module (10) comprises a light emitter (2) arranged to emit measurement light into the planar light guide (1), a light detector (3) arranged to receive measurement light from the planar light guide (1), and electronic circuitry (12) for generating digital measurement data (DPV) for the light propagation paths that extend to the light detector (3), wherein the digital measurement data (DPV) from the respective module (10) forms a subset of the projection values.
