METHOD FOR DETERMINING CLOSED TRAJECTORY BY MEANS OF LASER AND LASER LIGHT SENSOR, AND APPARATUS FOR DETERMINING CLOSED TRAJECTORY

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus that enable any misalignment of two shafts connected to each other via a joint to be determined with high accuracy, even in situations in which a measurement of the angle of rotation is impossible or is not possible with sufficient accuracy.SOLUTION: The invention relates to: a method for determining a closed trajectory (10) using a laser (12) and a laser light sensor (14) having a flat measurement field (16), which includes the steps A to G; and an apparatus (36) for determining the closed trajectory (10).
