Testing With Femtosecond Pulses
Calmar’s femtosecond laser sources are passively mode-locked fiber lasers. Passive mode-locking makes these lasers easier to operate than actively mode-locked lasers, as no external RF clock signal is required, and little or no warm-up time is needed. Temperature control is also less of an issue with passive mode-locked lasers. By Calmar Laser, Inc.

Smart Cameras from Vision Components now Programmable with Microsoft tools
Image processing expert Vision Components introduces a multi-level approach which considerably facilitates programming for VC's intelligent cameras. All VC machine vision libraries have been revised to run on PCs. Customers can continue to program in C or C++, but can now also use the Microsoft development environment Visual Studio 2010.
Better Nanoimages 'Spin' The Path To Improved Magnetic Memory
In work that could help make possible a faster, longer-lasting and lower-energy method of data storage for consumers and businesses, researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed a technique for imaging and studying a promising class of magnetic devices with 10 times more detail than optical microscopes.
What You Should Ask Before Investing In A Shortwave Infrared (SWIR) Lens
The military and industrial communities are
investigating shortwave infrared (SWIR) technology for
new and improved imaging solutions for a variety of
challenging applications. Indium gallium arsenide
(InGaAs) is a material often used for SWIR imaging due
to its high quantum efficiency and low dark current. This
advanced InGaAs material makes these detectors the
most sensitive imagers that operate in the shortwave IR
wavelength range at any given temperature. By MARC HANSEN
Global Optical Switching Market to Reach $15 Billion by 2004
Long-term demand for optical switching systems in the global telecommunications marketplace is going to surge upward from the current value of $543 million to reach $15.0 billion by 2004...
Superresolution Structured Illumination Microscopy (SR-SIM)
Superresolution Microscopy is a technique used to achieve an image resolution beyond the diffraction limit that is common in conventional light microscopes. This whitepaper discusses the superresolution structured illumination method and how it is used to achieve three dimensional resolution enhancement through a combination of optics and image analysis.
