摘要
En 中文
We propose a microlens array (MLA) construction method based on sub-channel optimal design and splicing, and an integrated projection imaging analysis method by using ray tracing and image warping. Our stop mask greatly improves imaging quality and eliminates crosstalk. We realize various projection distances, required projection imaging dimensions, and design optimization of sub-lens structures, providing freedom and possibility for MLA structure design requirements. Optical system chief ray tracing and sub-image generation is combined by using radial basis function forward image warping. Imaging distortion and overlap misalignment from short focal projection, multi-aperture offset, and complicated surfaces are perfectly corrected. Sub-image warping pixel mapping facilitates real-time replacement of projected images. We conduct substantial MLA integration imaging designs and precision analysis of different sub-aperture sizes, MLA sizes, and projection distances.
