ABSTRACT:
Velocimeter comprises a measuring volume (100) in a particle-laden fluid stream, means for brightly illuminating the measuring volume and means for measuring, based upon the light scattered by said particles when they are illuminated, the velocity of the said fluid stream, having a mosaic of optical fibers (10) and at least one optical system (101) for projecting a plane of the measuring volume onto the mosaic's input plane, the mosaic's outputs being connected to the velocity measuring means.
