Abstract
The present disclosure relates to a portable Raman probe that uses axicon lenses ('axicons'), grating axicons (“graxicons”), and other optical elements to collect spectra from substances behind non-opaque barriers using off-axis techniques. The portable Raman probe can also include a Raman spectrometer to analyze the collected spectra, and a spectra refinement machine-learning model to generate refined spectra from raw or noisy collected samples.
