Ceramic Lasers: Ready for Action
Feb 1, 2004 — Ceramic lasers have the potential to dramatically reshape today’s marketplace for solid-state lasers. These still-evolving devices offer high output powers and low losses that are competitive with today’s best commercial solid-state lasers. Yet, because ceramics can be fabricated quickly, they can be much cheaper. Moreover, the physical and optical properties of ceramics can be tailored, providing the opportunity to engineer lasers with properties and costs that cannot be obtained in...
Infrared Cameras Take Off in New Directions
Feb 1, 2004 — The principles behind infrared technology have not changed much since they were developed in the 1800s, yet advances in sensors, electronics and optics give rise to new applications for IR cameras every day. Higher speed, greater field of view,...
All IR Cameras Are Not Created Equal
Feb 1, 2004 — As media saturation spreads in the Western world, it is almost impossible to go anywhere without seeing some kind of a camera. This increase in camera use is highly evident in the infrared and night-vision market. However, it is important to note...
IR Imaging Assesses Damage in Mechanical Parts
Feb 1, 2004 — Testing the damage induced by fatigue loading to mechanical structures has traditionally been a challenge because it requires a number of samples and many mechanical tests to obtain an accurate figure of the damage mechanisms and their values. Using...
Low-Temperature Measurement of Shiny Metals
Feb 1, 2004 — Understanding and controlling the temperature of metals at all times during the manufacturing process is paramount if companies are to deliver products that are ever stronger and lighter. With new, unoxidized metals, the emissivity or radiation...
MCT-Based Cameras Uncover New Infrared Imaging Applications
Feb 1, 2004 — Infrared cameras based on mercury-cadmium-telluride (MCT) focal plane arrays are finding their way into a growing number of imaging applications. Typical of these applications is the benefit of new levels of sensitivity in certain IR spectral...
Infrared Thermography Streamlines Automotive R&D
Feb 1, 2004 — Infrared thermography inspection has become a powerful tool in the automotive research and development toolbox, not only saving time and expense, but also adding the unique advantage of radiometric imaging. Two recent examples of IR thermography in...
Aspherics Come of Age
Feb 1, 2004 — The use of aspheric surfaces offers the optical designer a way to achieve high performance with a minimum number of lens elements. However, the difficulty and expense traditionally associated with manufacturing high-quality aspheric optics has...
Laser Diode Manufacturers Turn Up the Power
Feb 1, 2004 — By one estimate, the global market for high-power laser diodes could approach $450 million by 2006 (Figure 1). So it perhaps comes as no surprise that quite a few players have entered the market recently. To compete, they must accommodate...
Fluorescence Detection Gains in Sensitivity
Feb 1, 2004 — The biotechnology and medical diagnostics industries could soon benefit from a technique that promises enhanced sensitivity over conventional fluorescence detection methods. Developed at the University of Maryland in Baltimore and called directional...
OFC 2004 Highlights Broadband Access and Cost-Cutting Technologies
Feb 1, 2004 — Broadband access, including fiber to the premises, and technologies that cut capital and operational costs are key issues that will be discussed at the Optical Fiber Communications Conference (OFC 2004) on Feb. 22 through 27 at the Los Angeles...
Hybridizing Spectroscopic Techniques
Feb 1, 2004 — Any given material can be characterized using a wide variety of spectroscopic techniques, each of which provides useful information. Depending on the material in question, of course, some methods are more effective than others. For example,...
Driving Down Detection Limits
Feb 1, 2004 — Identifying and quantifying the presence of metals is an important factor in determining environmental, public health and product quality. Metals can be either harmful or beneficial, and the amount of the metal present in a given substance often is...
Laser-Induced Breakdown Spectroscopy Moves Ahead
Feb 1, 2004 — Although the first laser plasma was generated in the early years of laser development, it was not until the late 1990s that laser-induced breakdown spectroscopy escaped the borders of scientific curiosity. One can simply describe it as a technique...
Near-Field Scanning Optical Microscopy and Spectroscopy Advance
Feb 1, 2004 — Although the rapid advance of scanning probe microscopy in the 1990s enabled routine imaging of unaltered samples at unprecedented nanoscale resolution, researchers still could not uniquely identify the chemical composition of materials and unveil...
Dalsa Wins Order for Custom Sensors
Feb 1, 2004 — Dalsa Corp. of Waterloo, Ontario, Canada, has received a $2.1 million production order for custom image sensors, due for delivery in the first half of the year. The chips will be integral to an imaging system that the international customer is...
Lockheed Martin Secures Contract for Bomb Kits
