超松弛法哈特曼傳感器波前重構(gòu)仿真分析

哈特曼傳感器是一種對環(huán)境要求低,測量精度高的光束質(zhì)量測量儀器,但傳統(tǒng)方法不能對任意形狀的光斑進(jìn)行波前重構(gòu),即光束質(zhì)量測量。文中采用超松弛法進(jìn)行計算機仿真,驗證了該方法能夠適應(yīng)任意入射形狀光斑的波前復(fù)原,從原理上解決了哈特曼傳感器測量任意
形狀光斑光束質(zhì)量問題。

Abstract :Hartmann sensor can measure the beam quality with high accuracy. It can not be used to measure irregular beam shapes with common methods. In the paper ,successive overrelaxation method is used to reconstruct the wave2 front of Hartmann sensor in computer simulation. It shows that the method can reconstruct wavefront for irregular beam shapes and solved the problem that Hartmann sensor can measure regular beam shape only in principle.
Key words :hartmann wavefront sensor ;wavefront reconstruction ;successive overrelaxation method
