Photoluminescence Improves LCDs
May 1, 1998 — Although electroluminescent, plasma and fluorescent technologies present certain advantages, liquid crystal displays (LCDs) continue to dominate the flat panel display industry. Liquid crystal's low power consumption, low-voltage operation and semiconductor compatibility make it the flat display of choice. But it also has its drawbacks: limits in brightness, efficiency and viewing angle. ETH Zurich's photoluminescent film absorbs optical energy and emits it as linearly polarized light....
Spatial Light Modulator Yields Full-Color Images
May 1, 1998 — A standard silicon wafer is the key to a technology that could make possible miniature, low-power, color displays, such as those used in portable or headmounted devices. Developed by researchers at the University of Edinburgh in the UK, the...
Flexible Controller Maintains Fiber Optic Polarization
Apr 1, 1998 — For nearly 200 years scientists and engineers have worked to exploit the inherent polarization of a light wave for mankind's benefit. From cutting edge research in laser cooling and atomic-transition gravitational wave detection to much that we take...
Names in the News
Apr 1, 1998 — Polaroid Corp. has appointed Hemang D. Dave as vice president of new ventures. Dave had been president and CEO of CMG Direct Interactive in Andover, Mass. Roy Grayzel is the new products development manager for Acton Research Corp.'s Optical...
Quantum Cascade Laser Lights a Fire at Photonics West
Apr 1, 1998 — Lighting a match with a laser doesn't seem like that big a deal, unless it's done at room temperature using far-IR light from a diode laser. It was in such a fashion that the inventor of quantum cascade laser diode architecture, Federico Capasso of...
Choosing Lighting for Industrial Imaging: A Refined Art
Feb 1, 1998 — As industrial imaging has grown in popularity over the past few years, so has the awareness that lighting represents a large part of a vision system's success. The primary function of lighting in industrial imaging is to make an object's features of...
Optical Coating Absorbs in UV Range
Feb 1, 1998 — Reducing stray light is a problem that engineers often encounter when designing optical instruments. One method of achieving this reduction is to apply absorptive coatings on an instrument's critical components. Applications for the coating are...
Pitch-Tracking System Provides Rare Insight
Feb 1, 1998 — NBC's all-star commentator lineup of Joe Morgan, Bob Costas and Bob Uecker had an advantage when calling each game of the 1997 World Series between the Florida Marlins and the Cleveland Indians. NBC viewers followed every pitch in the 1997 World...
FujiFilm Microdevices and Kopin Forge Alliance
Dec 1, 1997 — FujiFilm Microdevices Co. Ltd. has tapped Kopin Corp. of Taunton, Mass., to provide its CyberDisplay active-matrix liquid crystal display (LCD) for FujiFilm's digital camera chip sets. The new chip sets should lead to cameras that have advanced,...
Light-Shaping Diffuser Enables Miniature High-Resolution Display
Dec 1, 1997 — When engineers at Kopin Corp. began development of a flat panel display that would allow portable electronic devices such as pagers and cell phones to display text, video and graphics, their goals were simple construction with high-yield and...
Photonics Brings Dinosaur to Life
Dec 1, 1997 — SAN ANSELMO, Calif. -- Museums, faced with the dilemma of making their displays more interactive and paying top dollar for fossils, have turned to laser scanning as a solution to their troubles. "It's a shame, but museums are losing attendance,"...
Quick Screening Provides Key to New Luminescent Materials
Dec 1, 1997 — Researchers have long sought new compounds for ultraviolet-excited phosphors -- important for the development of flat panel displays and lighting. Because there are no reliable theories to predict the relation between composition and efficiency,...
Solid-State Diode Lasers Gain Ground
Dec 1, 1997 — Diode and diode-pumped lasers are about to find significant commercial applications, several experts on commercial and research photonics told a standing-room-only audience during a session at the Optical Society of America Annual Meeting in Long...
National Research Council's Competitiveness Task Force
Nov 1, 1997 — WASHINGTON -- The long-standing science and technology relationship between the US and Japan provided the backdrop for a report released in July by the National Research Council's Competitiveness Task Force. The focus was on the future and what US...
Digital Camera Saves Airline Time and Money
Oct 1, 1997 — 'United Airlines' System Aircraft Maintenance Control Group's job is to keep a fleet of 570 aircraft in service and well-maintained so the planes are safe and the airline remains profitable. It can be costly for airplanes to be grounded because of...
Holographic Reflector Provides Whiter, Brighter LCDs
Oct 1, 1997 — CAMBRIDGE, Mass. -- Scientists at Polaroid Corp. have developed a holographic reflector that promises to make color LCDs whiter and brighter. The secret lies in a transmission hologram that sits behind an LCD and reflects ambient light to produce a...
