Beam steering device

A beam steering device (300) for deflecting a beam of light is provided. The beam steering device comprises a first deflecting member (310), a rotating member (320), and a second deflecting member (330). For an incoming beam of light having components (303, 302) with their polarization parallel (303...

More Information
Summary:A beam steering device (300) for deflecting a beam of light is provided. The beam steering device comprises a first deflecting member (310), a rotating member (320), and a second deflecting member (330). For an incoming beam of light having components (303, 302) with their polarization parallel (303') and perpendicular (302'), respectively, to an optic axis (314, 334) of the beam steering device, the parallel component (303) is deflected by a first angle (304) when passing the first deflecting member. When passing the rotating member, the polarization (303', 302') of the beam of light is rotated by 90 degrees (303'' 302''). When passing the second deflecting member, the perpendicular component (302) is deflected by a second angle (305).
