集成成像三维（3D）显示技术具有连续视点、无需助视设备等特点，但普遍存在的视觉串扰现象严重影响立体观看效果。分析图像元在立体视区成像的有效像素区域，推导出图像元上的串扰图像区域分布的变化规律，提出一种立体视区完整的无串扰集成成像3D显示结构。精确设计具有渐变孔径的掩模板阵列，其既能完全透过有效像素光线，使光线向主视区和各阶立体视区成像，保留了集成成像立体视区分布的完整性，又能阻挡串扰像素光线的出射，消除了相邻视区间的串扰，实现了立体视区完整的无串扰集成成像3D显示。提出的结构简单易于实现，有助于集成成像显示技术的进一步推广。

Because of features such as continuous viewpoints and visual-aid elimination, a integral imaging three-dimensional (3D) display technology has gained widespread acceptance; however, its common phenomenon of visual crosstalk seriously affects the stereoscopic viewing effect. In this study, the effective pixel region of each element image that corresponds to the stereoscopic area was examined, and the corresponding crosstalk-pixel distributions were deduced. Then, a crosstalk-free integral imaging 3D display structure with a full stereo viewing area was proposed, and an accurately designed mask array with a gradient aperture was created. On one hand, the mask array penetrates the effective pixel light, allowing the light to be imaged onto the main view area and all the levels of the stereoscopic view area, thereby retaining all the integral imaging system stereo viewing areas. On the other hand, it blocks the outgoing crosstalk-pixel light, thereby removing crosstalk between adjacent view areas and achieving a complete crosstalk-free integrated imaging 3D display of the full stereoscopic view area. The proposed device is straightforward to build, and it will help popularize the integral imaging 3D display technology.
