Abstract:
A video display system includes a source of optical energy, a beam splitter, a baffle, an MxN array of mirrors and a screen. The source develops the first light beam along a first propagation path. The beam splitter is disposed in this first propagation path. The beam splitter is positioned to split the optical energy of the first light beam to develop a second light beam along a second propagation path. The baffle has a first face, a second face and a row of parallel slits. The slits are open between the first face and the second face and may extend either vertically or horizontally across each face of the baffle. Accordingly, there are either M rows or N columns of slits. The baffle is disposed in the second propagation path so that the second light beam illuminates the first face and passes through the slits to exit from the second face as a plurality of planar light beams along the second propagation path. The mirror array is disposed in a facing relationship to the second face of the baffle. Each row or column of the mirrors has an optically reflective surface in optical alignment with a respective one of the slits.
