Device for examining tissue with light of different wavelengths

摘要

The invention relates to a device for examining tissue with the aid of means (11 to 1n, 21 to 2n, 31 to 3n, 4, 5), which exhibit light, for injecting light of different wavelengths ( lambda 1 to lambda n) into the tissue to be examined, means (7, 81 to 8n) for detecting the proportion of injected (irradiated) light transmitted through the tissue to be examined, and evaluation means (12), to which the signals from the detection means (7, 81 to 8n) are fed, the evaluation means (12) determining from the signals, with the aid of stored data which correspond to the absorption of different tissue components, data which relate to the concentration of the different tissue components in the tissue to be examined. <IMAGE>
