ABSTRACT:
The invention relates to a device for measuring the light intensity of an object or object portion. The device comprises a dioptric central portion and a catadioptric peripheral portion that are independent from each other and that are suitable for delivering, from the light diffused by the object, two non-intersecting beams of the same kind, and a two-dimensional video sensor associated with an imaging device in order to obtain an image of the beams.
