Abstract: Optical systems are provided that include illumination sources, micro-mirror array optical modulators, and an optical element. The micro-mirror array optical modulators can selectively modulate light beams, redirect light by diffraction and reflection, and provide an output modulated light beam that exhibits a diffraction handedness dependent on the spectral bandwidth of the light incident thereupon. The optical element has a color dependent aperture that defines portions of output modulated light beams that are transmitted and remaining portions that are blocked. An efficiency and contrast of each the output modulated light beams acquired by the optical element can be independently determined by a narrow spectral bandwidth of each of the light beams, the spectral characteristics of the color dependent aperture, and the diffraction handedness of the micro-mirror array optical modulators for the associated spectral bandwidth.

Abstract: According to the present invention, a projection type image display apparatus enables control of a large amount of light masking through a light-masking unit while maintaining a uniform illumination distribution in an area to be illuminated by the illumination light. The apparatus uses two array lenses on which lens cells are arranged in matrix form, where light-masking unit masks the array lens installed on the light source side in their particular area. The light-masking unit adjusts the amount of light emitted from the light source. The light-masking area of lens cells adjacent to lens cells closest to an optical axis is made smaller than the light-masking area of other cells.

Abstract: Systems methods and apparatus for projection system including a control/illumination module and a separate projector head are disclosed. The control/illumination module can be disposed in the location separate from location in which the projector head is disposed and/or used. The projector head can be coupled to the control/illumination module via a control signal connection, and illumination transmission connection and an optional coolant connection. By separating the control/illumination module from the projector head module, many, if not all, noise and heat producing elements can be implemented in the control/illumination module, thus providing a smaller sized, quieter, efficient and lower maintenance projector head that can be installed in implementations in which extraneous noise, heat, and leaked light can be detrimental to the viewing experience.
