| Title: |
Beam Steering Apparatus |
| Abstract: |
Beam steering apparatus comprising an apparatus body and means in the body
for generating a beam. First and second rotatable reflectors are provided
for deflecting the beam in different directions, the beam being
deflectable by the first reflector onto the second reflector so as to
deflect the beam substantially in any direction. The apparatus is further
provided with a first motor for rotating one of the reflectors and for
driving a first input to a gearbox. A second motor is provided for driving
a second input to the gearbox, the gearbox having an output for rotating
the other reflector. The first and second motors are housed in the body.
The gearbox output rotates the second reflector via a drive belt. The
rotation of the first reflector induces rotation of the second reflector.
The gearbox inputs and output are arranged to compensate for the induced
rotation such that rotation of the second reflector by the second motor is
unaffected by any rotation of the first reflector.
