Compressive Sensing Time-Domain Raman Spectrometer for Depth Sensing of Diffusive Media

摘要

For the first time, we are proposing a compressive-sensing approach to time-domain diffuse Raman spectroscopy for depth probing of multilayer diffusive media. We built a spectrometer capable of both spectral and temporal acquisition with a single-pixel detector and tested it for depth sectioning on a bilayer tissue-mimicking phantom.
