Experimentally validated raman Monte Carlo simulation for a cuboid object to obtain raman spectroscopic signatures for hidden material by Periyasamy, Vijitha, Sil, Sanchita, Dhal, Gagan, Ariese, Freek, Umapathy, Siva, Pramanik, Manojit

“…In addition, we demonstrate through simulations the effects of the absorption and scattering coefficients of the layers, and that of the diameter of the excitation beam. The advantage of collecting light from all possible 4π angles, over other collection modes is that this technique is not geometry specific and molecular identification of layers underneath nontransparent surfaces can be obtained with minimal interference from the surface layer. …”
