Abstract
A MEMS laser scanner is disclosed for use in a near-eye display including an increased field of view (FOV). In embodiments, one or more polarization gratings may be applied to the mirror of the MEMS laser scanner, which polarization gratings may be configured according to the Bragg regime. Using light of different polarizations, the MEMS laser scanner is able to expand the FOV without increasing the range over which the mirror of the scanner oscillates.
