A Single-Pixel Hyperspectral Imager based on Digital Micromirror Device

This paper introduces a hyperspectral imager using a single-pixel detector. The imager employs a digital micromirror device and a scanning mirror for spatial and spectral encoding, respectively. Experimental results in the visible wavelength range are presented and the proposed imaging principle can also be easily applied to hyperspectral imaging at any other wavelengths.
