Air And Missile Defense System To Get Smarter Software

When a missile is launched against an enemy target, it would be nice to have a lot of good information about that target. But when "decision makers push the fire button, they may have very little data, and sometimes not timely enough data," said Col. Rob Rasch Jr., project manager, Integrated Air and Missile Defense Project Office, or IAMD, at Redstone Arsenal, Ala. "Nowhere in the current Army architecture is there a way to share information from all of our various sensors and weapons to have better integrated coverage," he pointed out, referring to situational awareness for those operating Patriot and other missile defense systems like those used for short-range air defense.

Bending Light with a Tiny Chip

Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at Caltech.

Demystifying Spectroscopy

Spectroscopy techniques date back to Isaac Newton’s first studies of light and today provide researchers with a better understanding of what happens at the atomic and molecular level when matter interacts with light. Advances in electro-optics, high-speed array detectors, inexpensive optical fibers and powerful computers have spurred the growth of miniature spectroscopy. This miniaturization has increasingly made optical spectroscopy the sensing technique of choice for many real-world applications.

CCD Cameras

Raptor Photonics (Co Antrim, Northern Ireland) has launched a new range of CCD cameras for fluorescence applications. Based on the new breed of Sony sensors, developed using Sony ExView HAD II sensor technology, (ICX674, ICX694, ICX814) these cameras offer a choice of resolutions (2.8MP, 6MP and 9MP) and are available in both mono and RGB. With pixel size of 4.54μm, these sensors provide ultra-sharp images. The cameras come in a range of formats, each offering different features for their intended users.

Spectral Test Station

The new McPherson (Chelmsford, MA) 310STS has efficient grazing incidence optics with light sources that work between one and 120 nanometers. Sources include electron impact solid anode type for SXR and windowless hollow cathode for lower EUV energies. The sources fit conveniently to the scanning entrance slit of a one meter focal length grazing incidence monochromator. The monochromator has adjustable apertures, accepts multiple diffraction gratings and has motor drive controlled by PC for simple selection of wavelength. The selected wavelength travels directly to devices under test. Connection to your experiment or to telescope calibration chambers (for example) is simple. Sample motion is required only as analysis requires.

Optical Coatings

L-3 Applied Optics Center (Dallas, TX), part of L-3 Communications, Warrior Systems, recently coated thirteen large optical elements for a major national telescope. The largest of the elements was over 27 inches in diameter and weighed over 300 pounds. The anti-reflective and highly reflective thin film optical coatings deposited by AOC on the various elements were specifically designed by Applied Optics Center to enhance the overall performance of the telescope, and to ensure its long-term mission success.
