Optical probes for medical applications are provided. The probe is devised so as to be able to be held in one hand. A basic version of the probe includes: a first excitation lighting source suitable for causing a fluorescence radiation of predetermined substances; a second visible lighting source, the first and the second source being devised so as to illuminate a common zone termed the intervention zone; a first photosensitive matrix sensor; and a second photosensitive matrix sensor. The first and second photosensitive matrix sensors are devised in such a way that, when the optical probe is arranged a predetermined distance from the intervention zone, the image in the visible spectrum of the said zone is formed on the photosensitive surface of the first matrix sensor and the image in the fluorescence spectrum of the said zone is formed on the photosensitive surface of the second sensor. A first variant of the probe includes only a single optical objective, a second variant only a single photosensitive matrix sensor, and a third variant makes it possible to work under polarized light. |
