Abstract
A system for projecting images has an illumination system for providing light, a spatial light modulator including an array of individually addressable pixel modulator elements with curved reflective surfaces, and projection optics for projecting the modulated light to form the image, wherein no focal planes of the projection optics are aligned to the reflective surfaces of the pixels.
Claims14
A projection system, comprising:
- an illumination system providing light;
- an array of reflective and deflectable pixels for modulating the light so as to produce an image, wherein each pixel comprises a micromirror having a movable mirror plate with a curved reflective surface and the curved reflective surfaces of the micromirrors define a focal plane;
- and
- projection optics for projecting the modulated light to form the image, wherein the focal plane defined by the curved reflective surfaces is not aligned to the focal plane of the projection optics.
