Rebuilding Principle Formula of Optical Triangulation Method of Displacement Measurement in View of the Lambert′ Theory
In view of the Lambert′ theory, the authors have rebuilt the principle formula of optical triangulation method for displacement measurement. Comparison has been made between the new formula and the old formula built on geometric optics. Using the new formula, analysis of the principle factors which affect the displacement measurement precision of optical triangulation method has been carried out. The experemental results has been reported. The methods has been suggested for decreasing and coorecting the errors.
