Fast wave-front reconstruction and stitching for high definition Hartmann wave-front sensor
摘要
Abstract
A physical model for high definition Hartmann wave-front sensor is build up, and the feasibility of using Hudgin model instead of Fried model in high definition Hartmann wave-front sensors is proved. The boundary problem caused by unknown sub-aperture slope is analyzed, and the corresponding edge processing method is introduced. The process of wave-front reconstruction based on discrete Fourier transform is numerically simulated, and the lossless reconstruction is achieved. In practical applications, the input wave-front may be discontinuous at the edge of the obscured part. Thus a wave-front stitching method u-sing least square solution is proposed. The main factors which slow down the speed of reconstruction are studied, and the way to improve the reconstruction performance is proposed.关键词
