Trends in Camera Design Increase Functionality
Aug 1, 2004 — Commercially available camera sensors are shrinking, perhaps driven by the camera-phone craze. Now common are 3-μm pixels with megapixel sensors that measure less than half an inch. Although beneficial for compact cameras, such small sensors are not ideal for machine vision or microscopy. The smaller pixel size reduces sensitivity, increases noise and requires more expensive optics. The benefit is the cost: The economies of scale in the consumer market make these sensors less expensive...
The Future of High-Speed Smart Cameras: Tomorrow's Interconnect
Aug 1, 2004 — In recent years, the high-performance camera market has enjoyed an explosion in new technology. With both CCD and CMOS sensors offering acceptable image quality and increasingly high frame rates, users have had a myriad of solutions to meet their...
A Smart-Camera Implementation of a Hardware-Based Neural Network
Aug 1, 2004 — Although machine vision technology that can solve simple problems has long been available, no machine vision system, until recently, could match a human’s ability to handle highly complex tasks that require sophisticated judgment — at least not at...
Camera Memory Allows Rapid Data Transfer
Aug 1, 2004 — In scientific and imaging applications, there is a trend toward CCD and CMOS camera systems with higher spatial resolution and frame rates. Designers have responded to the demand for greater detail and less magnification with more sophisticated...
Solid-State Heat-Capacity Lasers: Good Candidates for the Marketplace
Aug 1, 2004 — Under the support of the US Army's Space and Missile Defense Command, and in collaboration with industrial partners Boeing, General Atomics, DRS, Decade Optical Systems and others, we are developing high-average-power (100-kW class) mobile laser...
LEDs Meet Solid-State Electronics
Aug 1, 2004 — LEDs, once considered low-flux optosemiconductors, are now finding use in traditional, everyday lighting applications. Substantial increases in power efficiencies have enabled their use in traffic signals, automotive exterior lighting, signage and...
Siloxanes Find Niche in High-Brightness LEDs
Aug 1, 2004 — Solid-state lighting, such as LEDs, is an emerging platform that, in some cases, will replace conventional incandescent and fluorescent lighting. This technology has many benefits: It will increase energy savings, is more reliable and...
Industrial MicroscopyGets Down to Work
Aug 1, 2004 — It's a three-dimensional world for industrial microscopy these days, whether it is used to help monitor thin-film deposition processes or to inspect bumps on a circuit board. Regardless of the technique, building the 3-D image usually involves...
Total Interference Contrast Aids Thin-Film Engineering
Aug 1, 2004 — Many materials manufacturing applications today, including coating deposition, semiconductor production, microelectromechanical systems (MEMS) and micromachining, require precision surface step-height measurement. To measure simple surface height...
Differential Interference Contrast Adds Confocal Imaging Flexibility
Aug 1, 2004 — Confocal laser scanning microscopy continues to make inroads into industrial inspection applications as diverse as printed circuit boards and automotive components. A key reason is the technique’s analysis flexibility. Figure 1. Olympus laser...
3-D Coordinate Measuring Helps Inspect IC Packaging
Aug 1, 2004 — Semiconductor companies currently produce a large assortment of three-dimensional architectures for semiconductor integration and packaging. End users rely on diverse stacking strategies to conserve PC board space. Even stacking die to wafer and...
Technique Maps Complex Microsurfaces
Aug 1, 2004 — Recently there has been much interest in various noncontact methods for measuring surface profiles.1 One new technique, based on low-coherence scanning interference microscopes, offers several advantages over monochromatic interferometric...
Laser Writes Ferroelectric Domains in a Confocal Microscope
Aug 1, 2004 — Confocal microscopes are powerful tools for three-dimensional imaging on the submicron scale and, when combined with fluorescence and/or Raman spectroscopy, can yield local information about chemical composition and structural details. Because of...
Fiber Bragg Gratings: A Versatile Approach to Dispersion Compensation
Aug 1, 2004 — Chromatic dispersion compensation is recognized as one of the main challenges in high-data-rate optical communications systems. Dispersion directly affects the quality of the data transmission and causes a blurring of the bit stream....
Nanocrystalline Cerium Oxide Improves Glass Polishing Operations
Aug 1, 2004 — Performance improvements are increasingly being sought in a variety of technologically advanced polishing applications related to the optics and microelectronics industries. From the production of photomask blanks to the fabrication of memory and...
Optical Ceramics Look to Commercial Applications
Aug 1, 2004 — Stopping a projectile traveling at 2000 feet per second is no easy task. To do so, manufacturers of bullet-resistant glass rely on extra-thick glass and plastic laminates. But more thickness means added weight, which is not what you want when trying...
Silicon Carbide Is Poised to Enter the Mainstream
Aug 1, 2004 — NASA systems designers are always looking to minimize mass on solar system exploration projects because every gram comes at a stiff price. When they found a lightweight material that could be used to manufacture the structure and mirror substrates...
SPIE Bolsters Awards Program
Aug 1, 2004 — As SPIE approaches its 50th anniversary, the society has reportedly taken measures to increase the depth and horizon of its awards, scholarships, grants and fellowships. According to Osuk Kwon, chairman of the awards committee and director of...
