Method and apparatus for measuring profile of three-dimensional object

摘要: A method of measuring the profile a three-dimensional object including steps scanning surface to be measured with slit-ray, forming an optical image on imaging plane nonscanning type two-dimensional sensor which is composed plurality mutually independent photosensors, each time interval between when slit-ray passes predetermined point and reflected rays are received by any storing intervals in separate memory means one correspondence position photosensors determining from stored.
