Abstract

This paper presents a novel scheme for the purpose of minimizing delay time errors of a receiver of a time-of-flight distance sensor based on the principle of correlation. The nonrandom delay time error is reduced by means of an improved reference technique using alternatively activated target and reference photo diodes within the same receiver. Thus the accuracy of the sensor is considerably increased.
