Measuring fluorescence within a zone on a surface of biological tissue uses a probe that comprises first and second sensors that are constituents of corresponding first and second optical systems and that are fixed relative to each other. The first sensor is configured to detect fluorescent light emitted at said surface and the second sensor detects visible light. The measurement includes projecting a mark onto the zone, and, based on a position of an image of the mark on the second sensor, localizing and locating fluorescence detected by the first sensor in an image of the zone. The image is produced in visible light. The mark is a light mark that is detectable by said second sensor.
A method of localizing fluorescence within a zone on a surface of biological tissue using a probe that comprises a first optical system haying a first sensor configured to detect fluorescent light, a second optical system having a second sensor configured to detect visible light, and a marking-light source, wherein said first sensor is fixed relative to said second sensor such that an optical axis of said first optical system is not coaxial with an optical axis of said second optical system, wherein localizing said fluorescence comprises projecting a mark onto said zone at a center of said first optical system with said marking-light source, and, based on a position of said mark in a visible image of said zone acquired by said second sensor, localizing fluorescence within said zone by simultaneously displaying said visible image and a fluorescence image acquired by said first sensor.
An apparatus for measuring fluorescence in a zone on a surface of biological tissue, said apparatus comprising:
