We develop a high-speed compressive Raman imaging technology using a programmable binary spectral filter and a single channel detector to perform fast Raman imaging for detection and concentration estimation of know species over millimeters field of view. The technology enables Raman imaging with a pixel dwell time as short as few hundreds of microseconds. We report fast Raman imaging of pharmaceutical tablets and micro-plastics. We also present a novel fast line scan compressive Raman imaging scheme using the 2D digital micro-mirror device (DMD) to encode both space and frequency.
