Abstract

Computer-Aided Alignment (CAA) is an effective method for improving image quality of an optical system, which is implemented by aberration compensation technique. This paper studies some key techniques of CAA, including the mathematical model of CAA, the selecting of the aberration compensator, the establishment of sensitivity matrix and the solution of misalignment. A numerical simulation of CAA has been performed for a four-lens precision optical system to verify the ability and accuracy of the method. Comparisons of the image qualities between the pre-alignment and post alignment systems are also presented. These results indicate that the CAA method is feasible. It can not only meet the precision requirement, but also accelerate the convergence of alignment solutions. This method is realized by compensation among variables, so the variables are reduced and the time of alignment is saved.
