[Spectrometry for determining hematoma duration in vivo].

Spectroreflectometric measurements in the range of 430 to 700 nm were carried out in order to check this new method with regard to its application to determine time of haematomas in living humans. For this purpose 52 cases with artificial superficial skin haematomas and 40 patients with pure "monocle-haematomas" were investigated. Wavelengths of 560 and 580 nm indicate the best results. There are significant differences in cases with "monocle-haematomas" if the age difference of the haematomas is more than two days.
