©2002, IS&T—The Society for Imaging Science and Technology outer thin layer, epidermis, and an inner, relatively thick layer, dermis. For normal human skin, the absorption of the epidermis is dominated by a black pigment called melanin, though there are five different pigments in the skin.6 The spectral characteristics of different races or different individuals are due only to variation in the...

The translocation and absorption of 58Co (CoCl2) through a wound was investigated experimentally with mice. Physical and chemical skin damages became the objects of the investigation. Abrasion, puncture and incision were made for types of the physical damage. The chemical damage included both acid and alkaline burns. The absorptions of the radionuclide through the contaminated wounds were measu...

We present in this paper the decomposition of human skin absorption spectra with a Non-negative Matrix Factorization method. In doing so, we are able to quantify the relative proportion of the main chromophores present in the epidermis and the dermis. We present experimental results showing that we obtain a good estimate of melanin and hemoglobin concentrations. Our approach has been validated ...

Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...
