First Claim
Patent Images
1. A scene projector, comprising:
- an array of light emitting pixels disposed on a substrate;
a tunable filter element optically coupled to the array of light emitting pixels such that light emitted from the array of light emitting pixels is passed through the tunable filter element as filtered light; and
a spatial light modulator optically coupled to the array of light emitting pixels and configured to generate transmitted light by interacting with the filtered light to control at least one of an amplitude, a phase, and a polarization of the filtered light.

Abstract
A scene projector including an array of light emitting pixels, a tunable filter element, and a spatial light modulator. The tunable filter element is optically coupled to the array of light emitting pixels such that light emitted from the array of light emitting pixels is passed through the tunable filter element as filtered light. The spatial light modulator is optically coupled to the array of light emitting pixels and is configured to generate transmitted light by interacting with the filtered light to control at least one of an amplitude, a phase, and a polarization of the filtered light.
