Abstract

A device that can be used for in vivo fluorescence measurements by endoscopy or laparoscopy, including: an excitation light source illuminating an object, for example biological tissue, and inducing emission of emission light by the examined object, the emission light is, for example, a fluorescence light; a telemetry sensor emitting a telemetry light beam towards the object; a projector element to project the excitation beam and the telemetry beam directly on the object. The telemetry sensor can estimate a distance between the projector element and the object, which distance makes it possible to modulate intensity of the excitation light emitted by the object. When the object is biological tissue, this makes it possible to comply with illumination thresholds of biological tissue and to maintain an illumination of constant intensity. The projector element can be included at the end of a laparoscope or of an endoscope.
