For an advanced three-dimensional (3D) light field display, the 3D image information with correct spatial occlusion relation should be provided in a large viewing angle range. However, the optical distortion and the structural error are two key factors of the deterioration in image quality, which cause the serious deformation of 3D images, especially in large viewing angle. Here, the light path of spatial voxel is analyzed. The mathematical relationship between optical system parameters and spatial voxel positions is achieved. The aberration theory is used to analyze the optical distortion of single lenses. Due to the influence of optical distortion, the angle of the emitted light deviates from the ideal direction, which leads to the deviation of spatial voxel positions. The compound lens with aperture-stop is designed to suppress the optical distortion. The optical performance of optimized compound lens is evaluated. In order to further suppress the residual optical distortion and the structural error, a pre-correction method with the detection of optical path error is proposed. The correspondence between the pixel of display source and the spatial voxel is obtained. Based on the designed compound lens and pre-correction encoded image, a 3D light field display system is constructed. Experimental results demonstrates that the proposed method suppresses the optical distortion and the structural error. An undeformed 3D image with the viewing angle above 100 degrees can be achieved, which can find potential applications in biomedical imaging and visualization to enhance medical analysis and diagnosis.
