High-fidelity 3D visualization system for light field microscopy based on zonal-multiplexed holographic optical element-microlens array

초록

In this paper, we propose a high-fidelity three-dimensional (3D) visualization system for light field microscopy (LFM) that simultaneously acquires high-resolution two-dimensional (2D) images and 3D light field information through a zonal-multiplexed holographic optical element-microlens array (HOE-MLA) integrated into a single optical axis. The proposed system combines depth maps estimated from the light field data with high-resolution 2D images and texture information to reconstruct high-quality 3D visualizations of microscopic objects. The HOE-MLA is specifically designed to capture both light field data and high-resolution 2D images, encoded as different computer-generated holograms (CGHs) on the same holographic optical element, and can be fabricated using a holographic printing technique. This design enables the concurrent acquisition of complementary data, depth, color, and texture, which are processed by a robust image-processing subsystem to generate natural-view 3D reconstructions. The proposed system is experimentally validated using a simple optical setup and demonstrates high-quality 3D visualization performance. © 2025
