Abstract
(EN)
Disclosed is a scanning device which scans beams outputted from a light source. The scanning device is provided with: a beam collecting section, which collects beams outputted from the light source; a beam diffusing section, which is disposed on the output side of the beam collecting section, and diffuses the beams collected by means of the beam collecting section; a first scanning section, which is disposed between the beam collecting section and the beam diffusing section, and which scans the beams collected by means of the beam collecting section; and a moving section, which moves the beam collecting section and/or the beam diffusing section in the optical axis direction of the beam collecting section and/or the beam diffusing section, corresponding to the scanning angle of the first scanning section.

L'invention porte sur un dispositif de balayage par des faisceaux émis par une source de lumière. Le dispositif de balayage est muni : d'une section de collecte de faisceau, collectant les faisceaux émis par la source de lumière, d'une section de diffusion de faisceau disposée sur le côté de sortie de la section de collecte de faisceau et diffusant les faisceaux collectés par la section de collecte de faisceau, d'une première section de balayage disposée entre la section de collecte de faisceau et la section de diffusion de faisceau et balayant les faisceaux collectés par la section de collecte de faisceau, et d'une section de déplacement déplaçant la section de collecte de faisceau et/ou la section de diffusion de faisceau dans la direction de l'axe optique de la section de collecte de faisceau et/ou de la section de diffusion de faisceau, en correspondant à l'angle de balayage de la première section de balayage.
