title = "Study on computer-aided alignment method of reflective zoom systems",
abstract = "Computer-aided alignment is an effective method to improve the imaging quality of high-precision, complex, and off-axis optical systems. However, how to determine the misalignment quickly, exactly and constantly is essential to the technology of computer-aided alignment. Owing to the varying optical characteristics of a zoom system, sensitivity matrices are used in the alignment rather than a single matrix. Thus, the processing of sensitivity matrices is important for the computer-aided alignment of the reflective zoom system. So, the total least squares is proposed in order to solve the problems of the numerical instability and the result inaccuracy which result from the solution of the least squares method directly. Finally, the simulant calculation is processed using the numerical analysis model established in the essay. The results demonstrate that the computation method is rational and effective.",
