Visualization of real-time color-debugging pseudocolor-encoded phase variation with a photoelectronic processing technique

摘要

Abstract: A photoelectronic processing technique for visualization of real-time color debugging pseudocolor encoded phase variation has been proposed. It is based on the spatial filtering operation, the polarized modulation of linear polarization read out light passing through liquid crystal light valve (LCLV), real-time processing ability of the liquid crystal light valve, and manifold color debugging measures. The principle of this technique is discussed by using a simplified hybrid field effect mode of the liquid crystal light valve. Some color photographs of typical pseudocolor encoding phase variations using this technique are also presented. !12
