چکیده مقاله :
Spectral reflectance from layered skin tissue as a function of wavelength can provide valuable information about the skin's optical properties for diagnosing skin conditions. Monte Carlo and Henyey-Greenstein (HG) are two methods to model scattering in skin layers. However, the HG method is a simpler and widely used technique that assumes a single parameter to characterize the scattering phase function. In this study, we conducted simulations of scattering in six-layered skin tissue using Zemax software based on HG method. Our observations revealed increased penetration depth and back-scattered reflectance as the wavelength increased. We investigated reflectance patterns in different skin conditions by simulating mild solar damage, mild chronic dermatitis, and Mild solar damage with chronic inflammation. We recorded differences in the maximum intensity of reflected light in each condition. Additionally, we compared the backscattered reflections produced by incoherent and coherent light sources. The results of our HD simulation-based studies suggest that incoherent sources at infrared wavelengths could be advantageous for the analysis of skin disorders.
