Abstract

As a rule, Interferometers are used to test the Figure in the polishing phase of optical components. It could provide advance tutor suggestion for manufacturing. Various spatial points on the testoptical components will be given by interferogram analysis. Binary image is got from raw data. The edge of optical component is differentiated with a sobel exactly. A coefficient constraint condition is incorporated into the least squares method for geometric parameters of circles.The center coordinates and size of radius will be calculated by the method, and then the coordinate of the interferogram could be erected exactly.
