Abstract
The feasibility of a novel method for shape control of a reflector based on surface accuracy analysis using a stereo vision is demonstrated through experiments. In the control procedure, intentional deformations are added to a reflector surface by using surface adjustment mechanisms and the corresponding changes in surface accuracy are analyzed from the measured surface shape using an optical shape measurement system. Then the control inputs for the shape correction of the deformed reflector are directly determined from the information on the surface accuracy. Some experiments are performed and their results show that deformations of the reflector are corrected properly by the developed method when its shapes are measured at appropriate points.
