Grating-based coded aperture compressive spectral imaging to reconstruct over 190 spectral bands from a snapshot measurement

Abstract: We report snapshot compressive spectral imaging using grating and coded aperture. Vision-Transformer based deep learning algorithm is developed for high quality reconstruction. Experimental results demonstrate that over 190 spectral bands can be reconstructed from a single measurement from 485nm to 657nm with spectral accuracy about 2nm, and spectral resolution up to 1.5nm.
