Paper Abstract

A portable proof-of-concept prototype device for single snapshot capturing of four spectral line images has been designed, assembled and laboratory-tested. It comprises optical unit that ensures even illumination of the skin target area simultaneously at four laser wavelengths - 450 nm, 523 nm, 638 nm and 850 nm, double-camera image recording system, micro-computer managed operation system and a touch-screen display for image control and displaying the concentration distribution maps of four skin chromophores - melanin, oxy-hemoglobin, deoxy-hemoglobin and bilirubin. Besides, the device captures skin auto fluorescence image at 405 nm laser excitation to separate seborrheic keratosis from other pigmented skin lesions. Skin chromophore maps are calculated offline by an external computer.
