Abstract:

A miniaturized spectro-polarimetric (SP) imaging system for skin imaging will be presented that uses liquid crystal (LC) devices to control the wavelength and the polarization. When linearly polarized light illuminates the skin, part of it is backscattered by dermal layers and rapidly depolarized by birefringent collagen fibers. As the photon penetrates deeper into the tissue, it will experience more and more scattering events; hence the depolarization depends on the penetration depth. The penetration depth and amount of depolarization depends on the wavelength of the incident light. Hence there is strong polarization and wavelength dependence of light scattered from the skin, meaning that SP imaging is required. LC devices help grabbing polarization and spectral images almost in real time; hence they have the potential of making such biomedical optical imaging systems a reality in clinical usage. Preliminary results of imaging skin abnormalities will be presented and discussed.
