To address the major challenges to obtain high spatial resolution in snapshot hyperspectral imaging, 3D printed glass lightguide array has been developed to sample the intermediate image in high spatial resolution and redistribute the pixels in the output end to achieve high spectral resolution. Curved 3D printed lightguide array can significantly simplify the snapshot hyperspectral imaging system, achieve better imaging performance, and reduce the system complexity and cost. We have developed two-photon polymerization process to print glass lightguide array, and demonstrated the system performance with biological samples. This new snapshot technology will catalyze new hyperspectral imaging system development and open doors for new applications from UV to IR.
为应对在快照超光谱成像中获得高空间分辨率的主要挑战，已开发出3D打印玻璃光导阵列，以高空间分辨率对中间图像进行采样，并在输出端重新分配像素以实现高光谱分辨率。弯曲的3D打印光导阵列可显著简化快照超光谱成像系统，实现更好的成像性能，并降低系统复杂性和成本。我们已开发出双光子聚合工艺来打印玻璃光导阵列，并通过生物样品展示了系统性能。这种新的快照技术将推动新的超光谱成像系统发展，并为从紫外到红外的新应用打开大门。
