Abstract

A hyperspectral imaging system based on compressed sensing has been developed to image in the 0.9–2.5 μm shortwave infrared wavelengths. With a programmable digital micromirror device utilized as spatial light modulator, we have successfully performed spectrally resolved image reconstruction with a 256-element InGaAs linear array detector without traditional raster scanning or a push-broom mechanism by a compressed sensing (CS) single-pixel camera approach. The chemical sensitivity of the imaging sensor to near-infrared (NIR) overtone signatures of hydrocarbons was demonstrated using hydrocarbon and ink patterns on glass, showing spectral selectivity for the chemical components. Compared to point-by-point raster scanning, we show that the CS scheme can effectively accelerate image acquisition with lower but reasonable quality.
