Abstract:
An apparatus for detecting tumorous tissue, comprising:at least one first excitation light source for emitting a first excitation light of a wavelength of between 300 nm and 314 nm; at least one optical fiber for guiding said first excitation light to an object field of the tissue to be examined; at least one lens for projecting an auto-fluorescence signal and/or remission signal of said tissue, generated by means of said first excitation light, to a CCD or ICCD chip of a camera; at least one data processing system for processing signals transmitted by said camera wherein: said lens includes a ridge prism and is capable of processing UV light, said lens generates at least two images of which at least one image represents the UV range and another represents a different wavelength range of the auto-fluorescence signal and/or of the remission signal of the object field.
