Abstract
An optical apparatus of this invention comprises a first spatial light modulator, an array of imaging elements, and a plurality of light sources, and an image surface. Each of the imaging elements of the array is arranged to form an image of the plurality of light sources via the spatial light modulator at a respective position on the image surface.
Claims43
An optical apparatus comprising a first spatial light modulator having a plurality of individually controllable pixels, an array of imaging elements, a plurality of light sources, and an image surface, wherein each of the imaging elements of the array is arranged to form an image of each of the plurality of light sources through a corresponding pixel of the spatial light modulator at a respective position on the image surface, and optical paths of each of the images of the plurality of light sources are overlapping through the respective pixels.
An optical apparatus comprising a first spatial light modulator, an array of imaging elements, a light source for illuminating the first spatial light modulator, imaging means, a second spatial light modulator, and an image surface, wherein the imaging means is arranged to form an image of the first spatial light modulator on the array of imaging elements via the second spatial light modulator and each of the imaging elements of the array is arranged to form an image of the second spatial light modulator at a respective position on the image surface.
