Abstract
The invention relates to an optical remote sensing system (2) comprising: a laser source (10) configured to generate a laser beam; an emission stage (12) configured to shape the laser beam for propagation in a probing medium (8); a collection stage (20) configured to collect light scattered by the probing medium (8); at least one photodetector (28); and for each photodetector (28), a plurality of optical fibers (30) configured to carry a portion of the light collected by the collection stage (20) to said photodetector (28), an input (34) of each optical fiber (30) being positioned such that said photodetector (28) is the conjugate, through said optical fiber (30) and the collection stage (20), of a distinct point in the probing medium (8).

Claims
5. System (2) according to any one of claims 1 to 4, wherein, for at least one optical fiber (30), an optical axis (A4) corresponding to the level of the respective input (34) is parallel to an optical axis (A2) of the optical collection stage (20).
6. System (2) according to any one of claims 1 to 4, wherein, for at least one optical fiber (30), an optical axis (A4) corresponding to the level of the respective inlet (34) passes through an optical center of the optical collection stage (20).
