An Optoelectronic Method of Contactless Measurement of the Profile of the Surface of Large Complexly Shaped Objects

摘要

A new optoelectronic method of contactless measurement of the profile of the surface of large complexly shaped objects distinguished by a high degree of reliability and resistance to variations in the optical properties of the surface of objects over a broad range and to additive noise in the images is proposed. The method utilizes structurized illumination, phase triangulation, and identification of phase images with stepwise shift.
