Claim 0:
1. A reflector device configured to reflect incident luminous radiation of wavelength λ, the device comprising a supporting base whereon are assembled:
a partially transparent mirror, having a partially reflective front face that reflects a fraction of the incident luminous radiation on the front face;
luminous radiation scattering means configured to scatter luminous transmitted radiation that traverses through the partially transparent mirror and emerges via a rear face of the partially transparent mirror, the rear face being opposite the front face; and
holding means for holding the partially transparent mirror, wherein the holding means enable the partially transparent mirror to be pivoted about at least one axis,
wherein the wavelength λ is higher than 1250 nm,
wherein said device is a Light Detection And Ranging device,
wherein the partially transparent mirror has a reflection coefficient of the incident luminous radiation of at least 96%,
wherein the scattering means are disposed facing and away from the rear face, and
wherein the scattering means comprise a series of first collection strips, essentially flat, each provided with a first front face and a first rear face opposite the first front face, the first collection strips being aligned along an alignment direction, parallel with one another, and oriented so as to partially reflect, toward a first dissipator, the transmitted luminous radiation liable to be transmitted by the rear face.
