Spectral diagnostics and characterization of atopic dermatitis in children's health - A Hyperspectral Imaging System using an Acousto-Optic Tunable Filter
Abstract
Hyperspectral imaging with high spectral and spatial resolution can be used toanalyse material using spectroscopic methods. This technique can be applied tohuman tissue as a general purpose diagnostics tool and as an aid to medical personnel.The light propagation in tissue can be modelled in numerous ways, among others is the radiative transport equation (RTE) and its approximation the diffusionapproximation. The goal of this project is to assemble a camera system and usethese models to characterise atopic dermatitis in children health. This will be donetrough measurements with spectrometers and the assembled camera system andcompare the two.There was found a noticeable difference in the skin with and without atopic dermatitis,but quantitatively this has to be future explored. The proposed camera system wasfound not to be working, thought to be caused by internal reflection and miss alignment of optical components in the system.These results can, in the future, be applied to a real-time diagnosis system to detect,and reduce the over and under treatment of atopic dermatitis
