Patent ID: 8471221

Claim:
A device for measuring fluorescent radiation emitted by biological substances, said device comprising: a light source, a receiving unit, an evaluation unit that is coupled to the receiving unit, at least one emission fiber coupled to the light source, and at least one detection fiber coupled to the receiving unit, said emission fiber guiding excitation radiation to the biological substance, and the detection fiber receiving the fluorescent radiation excited on the biological substance and guiding said radiation to the evaluation unit, wherein the receiving unit further comprises a semiconductor sensor arrangement in which at least three sensors are arranged inside a surface for detecting fluorescent radiation emitted by the biological substance in wave length ranges that are separate from each other, the evaluation unit having stored therein data sets of at least two different reference measurements on at least two different biological substances, and the evaluation unit comparing the measured measurement values to the stored data sets and outputting a result relating to the pathological attacks of the examined biological substances and/or relating to the type of examined biological substances, wherein said data sets are stored in the form of multi-dimensional measurement values, wherein for each measurement value, the radiation intensity will be measured in multi spectral ranges.
