Lasers Help Identify Airborne Particles in Real Time
Aug 1, 1997 — RIVERSIDE, Calif. -- Around the globe, lasers are becoming one of the most accurate ways to measure wind speed and direction. Now researchers are using coherent beams to determine in real time and in situ the size and chemical composition of...
Machine vision steals the show
Aug 1, 1997 — TUCSON, Ariz. -- Machine vision successfully made the move from laboratory to industry. Now it looks as if it might make it in the theater as well. Arizona State University's Robb Lovell and John Mitchell have picked up where mainstream machine...
Boston University Opens $80 Million Photonics Center
Jul 1, 1997 — Wielding golden scissors, politicians and educators cut a ribbon and formally opened Boston University's state-of-the-art $80 million Photonics Center last month. On hand were Sens. Edward M. Kennedy of Massachusetts and Daniel K. Inouye of Hawaii....
Plastic Makes the Grade
Jul 1, 1997 — Plastic optics have taken a huge leap taken since the 1960s, when, a plastic magnifier epitomized the technology's high end. Today, the plastic diffractive optics landscape can only be described as dynamic.Plastic diffractive optics are finding...
Telecentric Lenses: Gauge the Difference
Jul 1, 1997 — For decades, engineers developing metrology instrumentation have used telecentric lenses in their products. Contour projectors and optical comparators, for example, owe much of their measurement capability to these unique lenses.Over the past decade...
Glass Aspheric Lenses Offer a Practical Solution for Bar-Code Scanners
Jun 1, 1997 — Bar-code scanning devices rely heavily on laser diode lighting systems to record data, and product designers are looking closely at ways to increase efficiency and reduce costs.Circularizing the elliptical beam from a laser diode for precise...
Researchers Predict Multicolor LED World
Jun 1, 1997 — ROCHESTER, N.Y. -- Dreams of ultrathin displays for computer and television screens could become a reality, thanks to a plastic light-emitting diode that emits light in several colors.LEDs are everywhere; clock radios, microwave timers, dashboard...
Colorful Laser Aims at Inspection, Displays
May 1, 1997 — LOS ALAMOS, N.M. -- Laser displays and semiconductor inspection could be the future applications for a fiber-based solid-state laser that emits in the red, orange, green or blue.The discovery was, in large part, an accident. Timothy Gosnell and Ping...
Machine Vision System Inspects Displays Online
May 1, 1997 — Portable equipment such as mobile telephones, electronic organizers and handheld games has become widely available. Most of this equipment uses displays that have been custom made to suit each individual application.The requirements for inspecting...
Measurement System Ensures that Black Is Black on Displays
Apr 1, 1997 — Conventional techniques of assessing contrast in displays fall short and often vary depending on reflections that caused "veiling glare" in the measurement device's optical system. Researchers at the National Institute of Standards and Technology...
Photonics Eyed To Cut Light Bills
Apr 1, 1997 — OAK RIDGE, Tenn. -- Using collectors to gather sunlight and optical waveguides to transport the light, researchers at the US Department of Energy's Oak Ridge National Laboratory have put together the first pieces of a hybrid lighting system that...
Stereo Displays Add A New Dimension to Work
Apr 1, 1997 — If commercially available stereoscopic displays could work without special glasses and be viewed from virtually any angle, by any number of people at once, we would probably view all three-dimensional data stereoscopically. Alas, such a technology...
On-Line Inspection System Produces 99% Satisfaction
Mar 1, 1997 — The thought of inspecting a million cans of food a day -- almost 700 cans per minute -- is daunting even with the advantages of today's high-speed automation. And when you add to the job a goal of 99 percent overall product quality and production...
Partnership Targets Laser Patterning for Flat-Panel Displays
Mar 1, 1997 — General Scanning Inc. of Watertown, Mass., and an undisclosed industry partner are developing a novel laser patterning system for use in the manufacture of flat-panel displays. The company will design and build a prototype system to prove the...
World Trade Pact Gives Photonics a Boost
Feb 1, 1997 — SINGAPORE -- Designed to even the global playing field, the Information Technology Agreement signed in December by 28 member countries of the World Trade Organization removes tariffs on many high-tech products, which should result in major gains for...
dpiX Wins Military Contract to Develop High-Resolution LCD Technologies
Jan 1, 1997 — The Defense Advanced Research Projects Agency (DARPA) has awarded a $2.75 million contract to dpiX, a subsidiary of Xerox, to develop high-resolution, reflective-mode display technologies for strategic and tactical information applications. The...
High-Resolution Technology Opens the Door to New Displays
Jan 1, 1997 — SUNNYVALE, Calif. -- A fundamentally new approach to display technology may revolutionize those alphanumeric readouts on phones, microwaves, pagers and dashboards. In response to increasing demands for higher information content and higher...
Holographic Light-Diffusing Technique Could Improve Flat-Panel Displays
Jan 1, 1997 — A novel holographic light-diffusing technology promises to improve lighting in flat-panel display and specialized flashlight applications. Developed by Physical Optics Corp. of Torrance, Calif., the technique helps shape diffuse light beams by...
New Phosphor View Promises Display Advances
Jan 1, 1997 — ALBUQUERQUE, N.M. -- A fresh insight into the nature of phosphors promises brighter, more colorful displays and, ultimately, a challenge to liquid crystals for dominance in the portable display market, say scientists at Sandia National...
Smart Lightpipe Designs Provide Cost-Effective Optics
Jan 1, 1997 — For a technology that doesn't get much respect, lightpipes are undergoing remarkably rapid applications growth. Lightpipes carry light from sources -- incandescent or fluorescent lamps or light-emitting diodes -- to illumination tasks. Applications...
Virtual Reality Goes to College
Dec 1, 1996 — The business of educating students at all levels of learning is growing more complicated as the world grows more complex. Today's students learn not only with traditional lectures and reading assignments but also with lab projects, video and...
