[Forensic applications of human skin spectral remission analysis employing a movable integrated sphere (author's transl)].
Spectral remission analysis has been known for long in the medical sciences [1,2,3] but has gained practical importance only in the last years due to the existence of modern techniques and components [4,5]. In this paper a method is presented which enlarges the range of applications of spectral remission and transmission analysis for wavelengths between 380 and 1100 nm considerably. This is achieved by a novel conception of the measuring instrumentation, the advantages of which are discussed and compared with the conventional technique. In detail these advantages are a) employment of a movable instead of a fixed detector (integrated sphere) b) illumination of standard and probe with radiation from a common source c) considerable increase of sensibility due to the use of selective lock-in amplifiers. As a demonstration of the proposed method results are given for 5 different probes of human skin.
