定量分析了集成成像系统中显示面板与重构微透镜阵列之间的旋转角度装配误差对重构图像质量的影响。首先，根据集成成像的原理，利用几何光学和光线追迹理论，考虑光轴平移和像素信息错位，建立了旋转角度装配误差理论模型；然后，基于上述理论模型对旋转角度装配误差导致的集成成像系统质量降质进行仿真；最后，引入峰值信噪比，定量分析了旋转角度装配误差对重构图像质量的影响程度，并给出不同微透镜尺寸、显示面板与微透镜阵列的距离等参数下满足观察者观测容忍度对应的旋转角度误差极限。

We quantitatively analyze the effect of the rotational misalignment between the display panel and the reconstruction lenslet array on the reconstructed image quality in the integral imaging system . First , the geometric optics and the ray tracing theory are utilized to build the rotational misalignment theoretical model based on the integral imaging principle by considering the optical axis translation motion and the pixel information dislocation . Then , the degradation of the image quality in the integral imaging system resulted from the rotational misalignment is simulated on the basis of the model mentioned above . Finally , the peak signal-to-noise ratio is introduced to quantitatively characterize the influence degree of the rotational misalignment on the reconstructed image quality , and the rotational misalignment limitations are given corresponding to the HVS observable threshold for different system parameters such as the lens pitch and the distance between the display panel and the reconstruction lenslet array . Research results will provide theoretical support for the parameters design and assembly of the display module in an integral imaging system .
