Abstract

A distance sensor and a measured object are positioned at a known distance from each other. A measured distance between the distance sensor and the measured object is obtained from the distance sensor, where the distance sensor uses a plurality of signals at a plurality of angles to generate the measured distance. The known distance and the measured distance are compared in order to test the distance sensor and produce a test result.
