Abstract: The present invention relates to an endoscopy device comprising several light guides (1, 2, 3), each light guide comprising one or more optical fibres. The light guides are coupled with a sweeping system (4) arranged to direct an excitation light beam in alternation in one of the fibres of the guides from the proximal end of the guide comprising said one of the fibres. In this way, the proximal ends of the guides may make use of the same sweeping system, whereas the distal ends of the guides may be installed simultaneously in different zones of interest of an object or animal (10) under study for an almost simultaneous observation of the zones of interest. The invention also relates to an endoscopy method used in a device according to the invention. A device and a method according to the invention may be applied to quasi-simultaneous reflectance, fluorescence, multi-photon imaging of several areas of interest.
