ABSTRACT:
A sectional form measuring apparatus measures perfect sectional forms of an object to be measured. The apparatus comprises a plurality of detectors for receiving reflected lights from the surface of an object, and a plurality of optical fibers with focusing lenses and light sources mounted on opposite ends thereof, or the like for measuring distances from a reference axis to the surface of the object to obtain the sectional forms at a plurality of positions on the reference axis. A marker may be applied to a specified measuring position on the surface of the object, thereby indicating a surface form of the measured object.
