Seeing in the Dark: Defense Applications of IR imaging
Infrared imaging is used in many defense applications to enable high-resolution vision and identification in near and total darkness. Thanks to recent advances, optics companies and government labs are improving low-light-level vision, identification capability, power conservation and cost.
by Valerie C. CoffeyTowards an Integrated Chip-Scale Plasmonic Biosensor
Biosensing allows researchers to detect tiny amounts of harmful chemicals before they become major threats. These researchers are using advanced optical technologies to develop the biosensor of the future—a plasmonic-based chip-scale device that will allow for compact, inexpensive, ubiquitous and sensitive detection.

An Eye toward Multispectral Imaging
The mantis shrimp is a marvel of nature that represents a truly multispectral scanning system.
Optonetic: A Niche in Custom Coatings
A small company in Orlando’s optics hub takes advantage of local support and cutting-edge technology to provide customized thin-film coatings for a large range of customers.
Science in the United Kingdom: Sailing in Stormy Seas
Britain’s scientists and technologists met the government’s spending review with cautious relief— and questions.
Resumes and CVs: A Problem-Solving Approach for Scientists
Scientists are natural problem-solvers, so they’re in luck when it comes to preparing a resume or CV. Getting at the heart of how you can address problems for potential employers is the key to getting your foot in the door for an interview.
OPN Talks with Donald Keck
Our conversation with Donald Keck, CLEO:2011 plenary session keynote speaker.
Tiny Room-Temperature Plasmon Lasers
Researchers demonstrated a nanoscale plasmon laser that works at room temperature, in air.
Presidents of the Mid-1960s
During the mid-1960s, OSA was led by an expert on colorimetry (and a stickler for grammar) and a pioneer who first envisioned OSA as an international society.
OPN Talks with James Fujimoto
Our conversation with James Fujimoto, OCT pioneer and CLEO:2011 plenary speaker.
A Glass That's Tougher Than Steel
Researchers at two California laboratories have developed a metallic glass that has more resistance to bending and breaking than many types of steel.
Electron Microscopes Get Twisty
Researchers at a U.S. laboratory have created spiraling “electron vortex beams” that could lead to better electron-microscopy images of magnetic and biological materials.
Electromagnetic Liquid Pistons Could Aid in Adaptive Imaging
With simple fluid dynamics, researchers have created an electromagnetically driven liquid-piston system that could be used for small-scale adaptive optics applications.
