Presentation Abstract

Skin lesions affect between a third to a quarter of the world population and 10-15% of the visits to general practitioners relate to this organ. This shows an opportunity to develop technology designed for the diagnosis of dermatological diseases.

From the optical perspective, skin in all its’ layers have different or unique reflectance pattern that could help us to differentiate between normal healthy tissues, and any type of injury or pathology in skin. Optical techniques that characterize tissues have gained importance due to its noninvasive nature. This happens because skin has different compounds that absorbs a specific spectrum of light (chromophores).

Even though all the different tissues have different reflectance or absorption spectrums, they are constituted of specific physical structures that interact with a very particular light spectra, which brings the opportunity to reveal information that can be associated with any type of compound or structure that it can also be related to some type of pathology.

We propose a study to develop a diffuse reflectance spectrometer and the protocol that would allow the study of diffuse reflectance in skin, with the intention of obtaining a tool that will develop an alternative to existing pathological studies.
