“…In recent years, with the optical design and optical manufacturing technology continues to improve, the structure of the optical system from the traditional coaxial system to the off-axis [1][2][3] systems, making the optical system design and optical manufacture and optical alignment complexity unceasing enhance. Because of complicated optical system, the traditional optical assembly method is very difficult to achieve the required precision; CAA of mount optical system was proposed to solve the problem.…”

Determine the misalignment of optical element quickly and exactly is the key to the technology of computer-aided alignment (CAA). For alignment a three-mirror off-axis field bias system, the sensitivity matrix method was used to simulate the alignment process. The results of simulation show that the sensitivity matrix method was not convergence. A new CAA method to get misalignment was put forward; the misalignment was obtained by programming the function of optical design software CODE V's auto-optimization option. The system's alignment characteristic was analysis and made use of this new method put up a computer simulation. The results of simulation show that the misalignment determined by only once auto-optimization and guidable to alignment of this system. After alignment, the optical system produced a measured wave front error across the all image plane less than 0.08 waves RMS at λ=0.6328μm.
