Paper Abstract

The collimation of the measurement point on the inner and outer diameters of a large workpiece is a key technology in large diameter measurement, and it is a measuring difficulty yet to be well resolved home and abroad. This paper applies highly stabilized light produced by laser collimator to collimate the photoelectric detectors on the two magnetic localize is each adhered to an end of the diameter of the piece, meanwhile, use the interferometer to measure the distance between the center of the two photoelectric detectors, and obtain the diameter by geometric computation. Both the theoretical analysis and the experiment showed that the method is practical, with relatively high precision, and the relative error of the measuring system was less than 5×10-6, which is superior to the traditional mechanical measurement.
