AI Technical Summary

Technical Problem

Existing diffraction spectral array imaging systems suffer from low energy efficiency, poor imaging quality, large size, and complex and low-precision spectral reconstruction, making it difficult to meet the development needs of large-scale hyperspectral/hyperspectral array imaging.

Method used

A high-efficiency integrated diffraction spectral array imaging system is adopted, including a diffraction lens array module, a coupling integration module, a microfluidic lens array module, a detector module, and an electronic control module. Combined with a parallel spectral reconstruction algorithm, the diffraction lens array and the microfluidic lens array are connected by coupling a positive lens array, an aperture stop array, and a collimating lens array, and high-precision spectral reconstruction is performed using a 3D U-net network.

Benefits of technology

It improves energy utilization, enhances imaging quality, reduces system size, and achieves high-precision spectral reconstruction, meeting the needs of large-scale hyperspectral/hyperspectral array imaging.

Abstract

本发明涉及衍射光谱阵列成像系统及光谱重建方法,具体涉及一种高能效集成衍射光谱阵列成像系统及并行光谱重建方法,解决了现有衍射光谱阵列成像系统能量利用率较低、成像质量较差、体积庞大,以及光谱重建复杂且精度较低的技术问题。本发明提供的高能效集成衍射光谱阵列成像系统,采用耦合集成模块连接衍射透镜阵列模块与微流控透镜阵列模块,可避免二者直接耦合导致能量损耗过大的问题;同时,耦合集成模块包括耦合正透镜阵列、孔径光阑阵列和准直透镜阵列的三级次耦合阵列,结构简单、高效,且体积较小。本发明还提供一种并行光谱重建方法,通过左右路并行的空间结构同时校正PSF与光谱,并结合3D U‑net网络结构,实现衍射光谱的高精度重建。
