The invention refers to devices designed for use for skin status non-contact evaluation, namely for evaluation of distribution of skin pigment concentration and the subcutaneous microcirculation. The proposed device for skin status non-contact evaluation comprises: LED emitters of a number of spectrum bands, adapted for specific skin illumination according to the skin spectral characteristics; optical lens system for the skin surface imaging; device for skin image recording and conversion to a video signal, a processor for the control of skin irradiation mode, where the processor being adapted for sequential switching on and off spectral emitters in spectral image mode at the respective spectrum of light, switching on definite spectral emitters at monochromatic video mode by simultaneous video tape recording of the skin, and calculating at the mapping mode of the skin chromophores, microcirculatory and fluorophores photo-fading maps; memory device for image and video signal recording; output device for display of skin chromophore concentrations, microcirculation and fluorescence photo-fading maps. |
