Patent number: 7532651Abstract: A phase plate and lens modify light beams emitted by an array of lasers to form an efficient illumination source for a MEMS light modulator array. The phase of the electric field emitted by the lasers is modified such that the after passing through a lens the beam profile at the lens focal plane has an approximately rectangular shape appropriate for illuminating a light modulator array. The phase plate may be constructed from a glass plate with rectangular notches etched in it or with rectangular ridges formed on it. Furthermore a light source, such as a laser, may be coupled to an adiabatically tapered optical waveguide in which a phase adjusting block is introduced in analogy to notches in a bulk phase plate. Phase modified light beams output from the waveguide system have similar focusing properties to those passing through a bulk phase plate.Type: GrantFiled: May 2, 2007Date of Patent: May 12, 2009Assignee: Alces Technology, Inc.Inventor: David M.

Patent number: 7286277Abstract: Polarization light modulators are based on an interferometric design in which a polarizing beam splitter serves as a polarizer and analyzer. A polarization displacement device shifts orthogonally polarized light beams parallel to the long axis of their elongated cross sections. Phase shifts are imparted to the orthogonally polarized beams by linear array MEMS optical phase shift devices. The output of the light modulator is a line image which may be scanned to form a two-dimensional image. Features to improve brightness, contrast and overall compactness of design are disclosed.Type: GrantFiled: January 20, 2006Date of Patent: October 23, 2007Assignee: ALCES Technology, Inc.Inventors: David M. Bloom, Mark C. Peterman
