MEASUREMENT OF CONTACT WIRE WEAR BY LASER IN THE DAYTIME

This report describes a structure of measuring device of contact wire wear by laser in the daytime, and results of tests in the institute and on the inspection railcar. The measuring device of the contact wire wear by the laser system takes use of a monochromatic light, and scanning along the width of the contact wire uses a rotary mirror, so that the reflected light from it is detected by a photoelectric conversion element.
