The developed measuring device is an optical noncontacting system which permits rapid measurement of complicated interior dimensions based on the principle of triangulation. A laser beam is projected from a small head of the device to various points to be measured and the reflected light is automatically searched by use of a photodetector to establish polar coordinates. The polar coordinate values are then converted into rectangular coordinate ones with a microcomputer, and can be represented on a panel and also punched out on a teletypewriter.
