Light Field Camera with MEMS Scanners
First Claim
1. A light field camera device comprising an array of light field camera elements, each camera element comprising:
- (a) a scanner for scanning an input beam across a two-dimensional angular field;
(b) an input focus modulator for modulating the focus of the input beam over time;
(c) a radiance sensor for sensing the radiance of the input beam over time; and
(d) a radiance sampler for sampling the radiance of the input beam at discrete times;
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.
