Abstract: Image projectors with increased light intensity and methods for providing brighter images are provided. Image projectors, described herein, can provide the brightness while still providing any or all of compactness, low power consumption, and long lifetime.

Abstract: Herein is presented a catadioptric projector by combining a commodity digital projector with additional optical units. By using specially shaped reflectors and/or refractors, a catadioptric projector can offer an unprecedented level of flexibility in aspect ratio, size, and field of view. Also presented, are methods to reduce projection artifacts in catadioptric projectors, such as distortions, scattering, and defocusing.
