Abstract
The diagnosis apparatus according to the invention for the picture providing recording of fluorescing biological tissue by way of an endoscope contains a stimulation light source which beams spectral components suitable for fluorescence stimulation into the tissue through the endoscope. The fluorescent light reflected by the tissue reaches through the endoscope optics into a head piece where it is split into a green, and spacially separated from this, a red spectral component and falls each on one half of a CCD solid body of a highly sensitive black and white camera. In an electronic and processor component the video signals allocated to the green and to the red spectral component are processed into two separate processing channels in a manner such that the separately processed green-red video signals are simultaneously inputted to a color video monitor and here may be superimposed to a red-green monitor picture, which may show changes of tissue indicating disease, for example dysplasia, carcinomas in situ etc., in all organs which are endoscopically accessible.
