摘要
In this paper, we present a design method for MLA-based integrated projection imaging system. By combining ray tracing method and RBF (radial basis function) mapping method, both geometrical and optical information of the muti-channel projection system are efficiently obtained. A comprehensive image processing pipeline is proposed to address the issues such as misalignment of sub-projection-images, image distortion, and non-uniform illumination. Additionally, anti-aliasing technique is employed to avoid pixel loss during process of image predistortion. A large FOV (field-of-view) integrated system is designed with a telescope structure. We give two design examples for both illumination and imaging application to demonstrate the general ability of our design method. The illumination simulation results demonstrate that the integrated projection system achieves 0.4% distortion and 99% illumination uniformity.
