MINIATURE SINGLE ACTUATOR SCANNER FOR ANGLE MULTIPLEXING WITH CIRCULARIZING AND PITCH CORRECTION CAPABILITY

摘要

PROBLEM TO BE SOLVED: To provide a device comprising a scanner which may be used in, for example, angle multiplexing of holographic data to carry out a stationary optical center of rotation (OCR) scan; and a device comprising a scanner which may use a single reflective prism for circularizing a scanning beam, for carrying out a stationary OCR scan, and/or for carrying out an orthogonal scan for pitch control.SOLUTION: The present invention provides a scanner (400) comprising: a reflector component (412); means (408) supporting the reflector component (412) for pivoting with respect to the MCR to provide a scan which is stationary with respect to the OCR; means (416) for enabling the support means (408) to provide controlled pivoting of the reflector component (412); a magnet component (420) which causes pivoting of the reflector component (412) when actuated; and means (424) for actuating the magnet component (420) to thereby cause pivoting of the reflector component (412).
