摘要: An endoscope (1) with a shaft (2), a grip (3) connected to the shaft (2) at a proximal end region of the shaft (2), and a viewing region (4) formed in a distal end region of the shaft (2) by optical elements. The shaft (2) has at least one proximity sensor (5), of which the measuring region lies at least outside the viewing region (4), preferably in such a way that the measuring region of the proximity sensor (5) covers at least the distance of the lateral region of the distal end region. The endoscope has an evaluation device (6) which is configured to generate a warning signal when a definable distance threshold value is undershot.

摘要: For an imaging method for presenting fluorophores (5) by optical excitation, spontaneous emission of fluorescence and detection of same, a single, conventional sensor (6) is used having at least two color channels, which detect an excitation light used to excite the fluorophore (5) and the fluorescence emitted by the fluorophore (5) with different sensitivities. Due to the different spectral distribution of the sensitivity of the color channels, it is possible to separate the component of the excitation light from the component of the fluorescence, in particular in a specific pixel, from one another by processing output signals of said color channels, in particular by conversion into a color space and/or by calculation of color saturation values. From this, the intensity of the fluorescence can be deduced, preferably taking account of a relative luminance measured by the color channels, even though reflected excitation light reaches the color channels, in particular in an unfiltered manner.
