摘要
集成成像3D显示是一种运用微透镜阵列从不同方位对三维物体记录和重构的真三维显示技术,针对集成成像3D显示技术景深不够、微透镜之间间隙透过的杂散光引起干扰导致的重构图像质下降等问题,本文设计新型微透镜阵列结构(双层针孔/微透镜组合阵列结构)以减少杂散光并增加集成成像3D显示的中心深度平面的个数以提高集成成像的景深。根据集成成像原理,确定双层针孔/微透镜组合阵列的参数,利用Tracepro光学仿真软件对集成成像3D显示过程进行仿真﹐结果表明,双层针孔/微透镜组合阵列能有效地较少杂散光﹔当两层微透镜阵列间距为5 mm时,本文系统获得的景深比传统系统大20 mm左右,即双层针孔/微透镜组合阵列结构能够实现在减少杂散光影响的同时又增加集成成像的景深。
Integral imaging 3D display is a true three-dimensional display technology that records and reconstructs three-dimensional objects from different orientations using micro-lens array.In view of the problem of insufficient depth of field in integral imaging 3D display technology and the reduction of reconstructed image quality caused by stray light from the gap between micro-lenses,a new structure(double pinhole/micro-lens array) was designed to reduce stray light and at the same time to increase the number of center depth planes for integral imaging 3D display,which could increase the depth of field for integral imaging system.The designed parameter of double pinholes/micro-lens array was determined according to the integral imaging principle,and the integral imaging system used double pinholes/micro-lens array was simulated by TracePro.The results show that,the double pinholes/micro-lens array could effectively reduce stray for integral imaging system,and the depth of field of this system was about 20 mm larger than that of the traditional system when the distance of the two layers of double pinhole/micro-lens array was 5 mm.That is,the double pinholes/micro-lens array can increase the depth of field for integral imaging,and improve the quality of the reconstructed image.
