greater arc lamp with a smaller imager in a two-stage system that includes two imagers in a row the use of the system

摘要

projection system in order to maintain good lamp life is improved by using a higher contrast and reduced lamp has a defect. Projection system uses two imagers, the first imager is larger to accommodate larger sized lamp to the first imager, a second imager is smaller. The first imager has a matrix of pixels for modulating light on the basis of the light between the pixels to form a first modulated matrix. Second imager has a matrix of pixels corresponding to the first imager pixel to modulate the first modulated matrix of light on the basis of the light between the pixels to form a second modulated matrix. Second imager has a smaller size than the first imager size. Relay lens set provides a magnification of less than 1.0 second to already transit the light of each pixel of light in the first modulated matrix onto a corresponding pixel of my.
