An Economical Non-Invasive Epidermis Thickness Measurement by the Application of Oct
Journal Title: International Journal of Electronics Communication and Computer Engineering - Year 2018, Vol 9, Issue 2
Abstract
The skin is the largest multifunctional organ in the body. It behaves as a protective physical barrier by absorbing UV radiation, preventing microorganism invasion and chemical penetration, and controlling the passage of water and electrolytes. There is always a need for developing a novel application for epidermal thickness estimation by non-invasive methods. Non-invasive methods such as Montecarlo method, Infrared diffuse reflection spectroscopy, Infrared light method, Pulsed Ultra Sound, Optical Coherence Tomography, Laser Scanning Microscopy are some of the widely used methods for epidermis thickness estimation. A cost effective non-invasive method to determine epidermal thickness from the intensity of light transmitted in visible region is proposed. Light is passed through the epidermis layers, and then measured what is transmitted back out of the surface. It is observed that transmittance is linearly dependent on the thickness of the epidermis and thus the method can be used for thickness estimation.
