Abstract
Devices and methods to perform Raman spectroscopy with a structured excitation profile to obtain a Raman excitation map. A device includes a broadband light source to emit a broadband light beam and excitation optics to disperse the broadband light beam to strike a sample as incident light according to a structured excitation profile. The device further includes analysis optics to collect scattered light scattered by the incident light striking the sample, block Rayleigh scatter from the collected scattered light in a manner complementary to the structured excitation profile, and direct Raman scatter from the collected scattered light to a sensor to generate a signal to form a Raman excitation map.
