Abstract

PURPOSE:Obtain deformation quantities or displacement quantities accurately non-contact by making images of the object and reference scale by an optical system which arranges a pinhole at the focal position of a convex lens and by converting these images into electrical signals by a photoelectric converter to compare with reference patterns.
