RGB Source Powers Up Laser Projection Displays
Jun 1, 2004 — Despite being considerably more expensive than TV sets, liquid crystal display projectors are finding their way into many homes. Their large projection area and deep color saturation generate something close to a cinematic experience in the living room. To keep their customers, movie theaters will have to provide an even better show. Although nearly all theaters currently rely on old-fashioned film projectors, digital laser projectors can provide a superior moviegoing experience because they...
Light Tamers
Jun 1, 2004 — From sophisticated deep-UV steppers to indoor-outdoor lighting applications, passing through rear-projection television screens and consumer electronic displays, one finds a common optical component: diffusers. These devices homogenize and...
Cleaning Standards for Fiber Optic Connectors Promise Time and Cost Savings
Jun 1, 2004 — A cleaning standard for fiber optic connectors could save industry millions of dollars annually. Contamination of connector end faces — in the form of something as simple as dust particles or fingerprints — can change light propagation through the...
Slashing the Costs of High-Precision Micromachining
Jun 1, 2004 — Nanosecond pulses from Q-switched, solid-state lasers have long been used in a variety of machining applications. More precise micromachining can be accomplished with the UV pulses from excimer lasers and with femtosecond pulses from ultrafast...
Tunable Telecom Lasers Promote Flexibility First
Jun 1, 2004 — With the telecom market showing signs of improvement, interest in tunable lasers is growing. Service providers are looking to the technology not just for sparing and inventory replacement, but also to reduce network operating costs in...
Manufacturing Strategy Combats Laser Price Pressures
Jun 1, 2004 — The manufacturing yield of single-mode lasers for modern fiber optic communications systems is surprisingly low, typically 50 percent or less, a problem that also can extend to tunable lasers. The source in a fiber optic communications system...
Standardizing Tunable Lasers
Jun 1, 2004 — In 2001, when the Optical Internetworking Forum (OIF) in Fremont, Calif., began work on a tunable laser implementation agreement, the specifications for commercially available tunable lasers — such as footprints, electrical specifications and...
Manufacturing Matters with Tunable Lasers
Jun 1, 2004 — One problem faced by manufacturers of full-band-tunable laser modules is the need for close cost parity with existing fixed or partially tunable devices. A key step in achieving this goal involves standardizing as much of the fabrication and...
Nondestructive Inspection: Choosing the Right Microfocus X-ray Source and Detector
Jun 1, 2004 — Of all nondestructive test methods, only x-ray technology enables visual detection of defects beneath the surface of opaque components, assemblies and finished products. This has made it an essential tool in multiple manufacturing sectors, including...
The Human Visual System Provides Clues to Better Object Recognition
Jun 1, 2004 — Machine-based vision systems, such as those used in the factory, at security checkpoints and in smart weapons, would greatly benefit if they could more closely match the remarkable ability of human vision for object recognition. Although generally...
Electron Multiplication CCDs Offer a Flexible Solution
Jun 1, 2004 — A recent advance in CCD technology is the introduction of electron multiplication or charge carrier multiplication CCDs. This technology is effective in applications requiring high light sensitivity, high spatial resolution and reasonably high frame...
Resolution Considerations for Color Imaging Technique
Jun 1, 2004 — Among the methods for color image creation and sampling, two popular techniques in common use are single-shot color mosaic sampling and three-shot color sampling. Each has its own advantages and disadvantages. With single-shot color mosaic...
CCDs Outperform Film in Rotating-Mirror Cameras
Jun 1, 2004 — Historically, the fastest framing cameras have been rotating-mirror film cameras, which can capture many millions of frames per second with resolution and image quality that is usually limited by the film grain. As a research tool, they have been...
Nanoptek Relocates
Jun 1, 2004 — Nanoptek Corp. has moved to Clock Tower Place, a Maynard, Mass., corporate complex that provides the facilities to support the company's recently awarded Phase II Small Business Innovation Research grant from NASA, along with space for expansion....
BU Is Building Nanophotonics Lab
Jun 1, 2004 — The Photonics Center at Boston University has begun construction of the $1.5 million NanoPhotonics Laboratory, which is scheduled to open in September. At the 1000-sq-ft facility, engineers and developers from various industries and areas of...
