Spectral imaging with dual compressed sensing

TL;DR

This paper presents an experimental spectral imaging method using dual compressed sensing, enabling the capture of spectral images with a single detector by compressing both spectral and spatial data.

Contribution

The novel dual compressed sensing scheme allows spectral imaging with a single detector, improving stability and consistency over previous methods.

Findings

Spectral and spatial information dimensions are both compressed.

Spectral images of colored objects can be reconstructed with a single point detector.

The scheme offers a stable and consistent approach to spectral imaging.

Abstract

We experimentally demonstrated a spectral imaging scheme with dual compressed sensing. With the dimensions of spectral and spatial information both compressed, the spectral image of a colored object can be obtained with only a single point detector. The effect of spatial and spectral modulation numbers on the imaging quality is also analyzed. Our scheme provides a stable, highly consistent approach of spectral imaging.
