The computer-aided alignment (CAA) is a key technology to align a precision optical system, which is generally a difficult and laborious work. However, many methods proposed has a weak point in that they cannot calculate the misalignments accurately if there are figure error in mirrors. In order to solve this problem, a new modified merit function regression (MFR) is developed, which can compute the misalignments even if the effect of figure error. Misalignments computation based on the traditional and modified MFR are tested in a typical two-mirror optical system, experimental results shows the correctness of modified MFR and its high calculation accuracy.
