Light field display with MEMS Scanners
First Claim
1. A light field display device comprising an array of light field display elements, each display element comprising:
- (a) a beam generator for generating an output beam of light;
(b) a radiance modulator for modulating the radiance of the beam over time;
(c) a focus modulator for modulating the focus of the beam over time; and
(d) a scanner for scanning the beam across a two-dimensional angular field, the scanner comprising a biaxial electromechanical scanning mirror comprising;
a mirror, a platform, an inner frame, and an outer frame;
the mirror attached to the platform via a post, the platform attached to the inner frame via a first pair of hinges, and the inner frame attached to the outer frame via a second pair of hinges;
the first pair of hinges arranged substantially orthogonally to the second pair of hinges, thereby to allow biaxial movement of the mirror;
the extent of the mirror larger than the extent of the inner frame.
