A new method for interference fringe scanning
A new method for fringe scanning has been given. In this method, the phase modulation is completed by inserting a rotating wave plate in the light source path. By this way, the disturbance in interference pathes is avoided. Compared with conventional methods, this new method has higher accuracy, higher reliability and lower cost.
