The illumination optical system can homogenize, shape, and direct a beam from the laser light source onto the grating light valve, and homogenization can occur in a cross-process direction.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

A light projection system, including a light source to provide an output beam of light, an angular light modulator (ALM) comprising a plurality of pixels, each pixel having an ON state and an OFF state, the ALM positioned to receive output beam on the plurality of pixels, and a processor coupled to the ALM. The processor is programmed to control a first set of the pixels to transition between the OFF state and the ON state while the beam is incident on the pixels. An amount of light is selectively directed in a direction by the first set. The processor is also programmed to control a second set of the plurality of pixels to remain in the OFF state while the beam is incident on the plurality of pixels. As a result, the ALM operates as a spatial light modulator and an angular light modulator of the beam of light.

The invention provides a projector calibration method for forming a spherical target image at a viewing point. The projector calibration method includes the following steps. A first preset image is projected by a first projector to a dome screen, and a first deformed image is obtained by capturing an image of the dome screen using a first camera. A spatial relationship between the first projector, the first camera, and the dome screen is calculated according to the first preset image and the first deformed image. A first prewarp image is generated according to a target image, a spatial relationship between the first projector and the dome screen, and a spatial relationship between the dome screen and the viewing point. Projection is performed by the first projector according to the first prewarp image. In addition, a projection system using the method is also provided.
