Compressive Raman imaging (Conference Presentation)

Paper Abstract

We develop a high speed compressive Raman imaging technology using a programmable binary spectral filter and a single channel detector to perform fast Raman detection and concentration estimation of know species over millimeters field of view. The technology is x100 times faster than commercial CCD based systems and x10 times faster than the EMCCD based systems. We report fast imaging of breast micro-calcifications, SERS particles, pharmaceutical tablets and micro-plastics. We also present a novel fast line scan compressive Raman imaging technique using spatial frequency-modulated illumination (SPIFI) that enables to encode space into the frequency domain to acquire single shot line images. We demonstrate the imaging and classification of three different chemical species at line scan rates of 40 Hz.
