Abstract :
This paper presents the effect of pattern slot size on measurement results of a noncontact laser sensor, in which the noncontact laser sensor is used to measure a precision stopping error of a moving object at a specific position, and to send measurement errors to a main control station through ZigBee wireless communication. Measurement accuracies for various vertical slot sizes are tested experimentally using an actual device developed in our laboratory, and the validity of the device is demonstrated for a moving object on a rail experimentally.
