Contribution to the measurement of optical characteristics of the skin.
The authors analysed the optical phase of radiation-skin interaction and proved different optical properties of in vitro specimens of normal skin and granular tissue from crural ulcers in the spectral region from 360 to 750 nm. In the visible spectral region, granular tissue showed reflectance lower by 25% on average than normal skin of comparable thickness. During measurement of penetration of He-Ne laser light with output of 50 mW, transmittance in granular tissue was higher by about 2.5 than in normal skin. In the thickest skin sample (19 mm), approximately 0.3% of incident light penetrated.
