Paper Abstract

Hyperspectral image acquisition is challenging due to its three-dimensional dataset consisting of two spatial and one spectral dimensions. Available spectral imagers are either based on spatial or spectral scanning or they sacrifice spatial and spectral resolution for snapshot imaging. Compressive Sensing techniques have already been applied to spectral imaging to enhance the image acquisition, but they still rely on multiple consecutive measurements. We utilize several diffraction orders of a novel diffractive optical element whose diffraction efficiency has been optimized for a broad wavelength range. Based on this diffractive optical element we design and compare novel compressive snapshot spectral imaging systems and present experimental results.
