Abstract (en)
[origin: FR2776049A1] The projector is composed of a central module (1) in a central hollow body (4) surrounded by a diffusing crown (2) formed from a number of hollow diffusion heads (3) arranged radially and concentric around the central part (4). The face of each diffusion head is covered by at least a wall through which the energy can pass. The hollow central body (4) communicates with the interior volume of each of the diffusion heads (3) via a passage passing through the lateral wall of the body (4). The body (4) contains a group of geometrical interior reflectors placed before an emission/reception window (8) which is the central opening formed in the rear wall of the central hollow body (4).
