This research was presented at SPIE Photonics West 2020 (February 2020) with the article titled: Quantification and influence of skin chromophores for remote detection of anemic conditions

(https://doi.org/10.1117/12.2545784)

Monte Carlo simulations were performed using Virtual Tissue Simulator (VTS) and Monte Carlo Command Line (MCCL) tools. The target was a two-layer model of the epidermis and dermis layers of the skin.

The optical attenuation properties quantifying the absorption and scattering in these layers are set according to two parameters:

- Amount of melanin in the epidermis

- Amount of haemoglobin in the blood-perfused dermis

The optical models are simulated at six wavelengths for 6 skin types (Fitzpatrick's scale) and two blood conditions, healthy and anaemic. This results in a total of 72 simulations

The simulation calculates the optical interaction of 10⁶ photons with the various combinations of optical properties. The resulting outputs show the absorption and fluence in the tissue model, and reflected and transmitted energy.
