Abstract
An array of light beam emitter sections comprises: a substrate having a surface divided into an array of sections; and a grouping of light emitters disposed at each surface section and configured to emit light beams at different emission angles with respect to the surface. Also disclosed is apparatus for establishing optical communication channels between the array of light beam emitter sections and an array of light detectors. The apparatus comprises a controller coupled to the arrays of emitter sections and detectors for mapping at least one light emitter of each grouping with a light detector of the detector array to establish optical communication channels between the arrays based on the mappings. Further disclosed is a method of establishing optical communication channels between the array of light emitter sections and array of light detectors by mapping at least one light emitter of each grouping with a light detector of the detector array to establish optical communication channels between the arrays based on the mappings.
