| 摘要 |
Apparatus for imaging autofluorescence in epithelial tissue to highlight regions of dysplasia is described. The apparatus includes a diode laser light source for producing excitation light that induces visible fluorescence in tissue and a reference light along with an optical combiner that combines the excitation light and the reference light onto a common optical path. In its simplest form the apparatus can be fitted to existing endoscope systems. A data processor produces a video image which is viewable by a clinician and due to the use of the dual lights includes a visible light image with a false colour overlay indicating areas where tissue fluorescence is reduced in comparison to that of normal tissue.
