Computer-aided alignment based on DWC wave-front testing

Computer-aided alignment(CAA)is an effective method to improve the imaging quality of high precision,complex and off-axis optical systems.The paper introduces the development and application of CAA,and summarizes the method of optical testing and optimizing.A computer-aided alignment method based on a high-resolution wave-front detector is proposed.The model includes the detection of the wave-front,calculation of disalignment and the aberration between the actual system and the designed system.By numerical experiments and comparison of the image qualities between the pre-aligned and post-aligned systems,the feasibility of the CAA method is demonstrated.
