Design, test and calibration of a portable spectroscopy system that applies the diffused reflectance and the induced fluorescence technique for dermatological medical purposes

Abstract

The purpose of this work is the design and test operation of a prototype system for taking measurements, alternatively, with both the techniques of the Diffused Reflectance Spectroscopy (DRS) and the Induced Fluorescence Spectroscopy (IFS). The whole setup is so constructed as to be portable, and the calibration and control of the system was used in order to be able to take skin tissue test measurements both ex vivo and in vivo. The same system is aimed at the final stage of development, to be used as a diagnostic tool for in vivo imaging and detection of non-melanoma skin cancers. The IFS measurements were made using suitable light sources of UV radiation (UV LEDs) and the same device can be used for making diffused reflectance measurements using a LED white light source
