Abstract

A systematic investigation of the combination of a reference path and a reference pixel as correction method for a systematic error induced by the light source of a time-of-flight (TOF) distance measurement sensor is presented. A change of the bandwidth of the light source, e.g. caused by drifting temperature of the used LEDs results in a bandwidth dependent distance error. The presented method allows reducing this error over a large operating range by ~97 %, i.e. to 3 %.
