夹缝光栅裸眼3D立体显示器的串扰研究

摘要

Auto-stereoscopic display can be realized with the aid of gratings,whose performance highly depends on crosstalk.There is a hot topic in the field of stereoscopic displaythat how to effectively analyze the crosstalk and reduce it.The paper derived formulae forquantitative calculation of crosstalk in grating based auto-stereoscopic display and then conceived a scheme for measurement of crosstalk based on a USB camera and with the help of matlab analyze.As the experiments show the measured crosstalk was in rough agreement with the theoretical simulation,which was less than 5%. The experiments result show that the method of quantitative research is workable.%狭缝光栅裸眼立体显示器是通过狭缝的遮挡效应来实现立体显示的,而串扰是决定其3D成像质量的关键因素,如何有效的分析其串扰进而减少串扰是立体显示研究一大课题.基于此目的,本文推导了狭缝光栅裸眼立体显示器中串扰的定量计算方法,并结合matlab对串扰进行了理论模拟,同时设计了基于USB摄像头的串扰测试方案,对设定的双视点后置夹缝光栅的串扰进行了实验测试,测试结果与理论模拟基本一致,其串扰度低于5%.实验结果表明此定量研究方法是可行的.
