【摘要】 分析了液晶电视(LCTV)的位相调制特性,采用将液晶电视和能产生台阶波前畸变的位相物体同时置于环路径向剪切干涉(CRSI)装置入射光路中的方法,在液晶电视屏上输入可产生畸变波前对应的互补波前的灰度图。实现了台阶结构畸变波前的补偿。更多还原

【Abstract】 LCTV’s phase modulation characteristics has been analyzed in this paper. Then a phase plate that can make a plane wave become a step-jump wavefront is inserted into a specific plane of incident light path of a cyclic radial shearing interferometer. And a gray distribution that can produce a conjugated wavefront of the step-jump wavefront was input the LCTV. The experimental result shows that the step-jump wavefront has been compensated ideally.更多还原
