Combined optical techniques for skin lesion diagnosis: short communication

Recent optoelectronic developments have helped scientists and dermatologists to design and improve equipments for the diagnosis of skin lesions. Among the numerous techniques which can be used in dermatology, optical coherence tomography (OCT) represents one of the best options, in terms of skin penetration depth and resolution, for retrieving morphological data of the skin. However, OCT has its own limitations and cannot offer the biochemical information of the skin. These data can be obtained with fluorescence spectroscopy, a non invasive, sensitive and real time technique. The present study aims to present the advantages of combining OCT with fluorescence spectroscopy for dermatological analysis. Examples of healthy skin and lupus erythematosus recorded with these techniques are given in this paper.
