Abstract
A light beam receiver includes a plurality of light beam detector elements, a plurality of integrator circuits that receive signals from the light beam detector elements, and a signal integral limiting integration time controller that is in communication with at least two of the integrator circuits so that an analysis of the light beam reception is determined. One embodiment provides a self-calibration function, using a plurality of light beam detector elements that generate output signals when receiving a light beam upon the light beam detector elements, an evaluation/control circuit that receives the output signals and is configured to substantially determine a position where the light beam impacts on the light beam detector elements, and at least one calibration light source that emits at least one light pulse that is coupled to the light beam detector elements. The light beam receiver performs a self-calibration function using the calibration light source.
