| Title: |
Beam Steering Device |
| Abstract: |
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).
