Abstract
A device for testing and/or adjusting a PDD or PDT system and/or for training on such a system comprises an illumination system emitting light which serves at least to stimulate a fluorescent dye and which may be directed to this end onto a tissue zone to be diagnosed and/or therapeutically treated, and an imaging unit which images the light arriving from the stimulated tissue zone. The invention is characterized by the provisions that a target is provided which reflects the light of the illumination system, and that the target comprises at least one light source which emits light within the wavelength range of the fluorescence spectrum of the dye.
