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 millimeter field of views with a pixel dwell time of few tens of µs only. The technology is x100 times faster than commercial CCD based systems and x10 times faster than the EMCCD based systems. We demonstrate rapid imaging of pharmaceutical tablets and microplastics.
