摘　　要：为了解决观看视角与亮度的相互制约关系,设计了一种基于渐变线光源的集成成像3D显示器,通过设置渐变线光源中每列线光源的宽度,优化微图像阵列中每列图像元的成像光路,建立了3D成像模型,通过几何光学推导了观看视角以及亮度的计算公式;研制了基于渐变线光源的集成成像3D显示实验装置,通过实验验证了可以在保持观看视角的前提下将3D图像的亮度提高为传统集成成像3D显示的4.5倍。To resolve mutual restriction of viewing angle and luminance, a high luminance integral imaging display based on a gradient line light source was proposed. The light paths of the elemental images in the element image array were optimized by adjusting the widthes of the line light sources in the gradient line light source. The imaging model of the integral imaging display based on the gradient line light source was established. The calculation formulas of the viewing angle and luminance were obtained by using geometrical optics. An experimental apparatus of the integral imaging display based on the gradient line light source was built. The experimental results prove that the luminance of the 3 D image is 4.5 times of the conventional one without loss of the viewing angle.
