<p>LIQUID COUPLED COLOR-TELEVISION IMAGE PROJECTOR In an image projector in which images from a plurality of image-producing devices are superimposed into a single projected image, the invention contemplates an improvement which comprises a housing including a wall and an enclosed chamber, the image-producing devices being associated with the housing wall so as to communicate with the chamber, a transparent window in the housing wall, and color-selective mirror means located within the chamber for directing the image from at least one of the image-producing devices to the window such that the images of the image-producing devices will be in superimposed registration with one another. A transparent liquid fills the chamber and contacts the image-producing devices, the mirror means, the window, and the housing wall, with the transparent liquid having a relatively high index of refraction for bringing the focal plane of the superimposed images in close proximity with the window. A projection lens system is associated with the window for projecting the superimposed images appearing at the window.</p> |
