Soldiers risk exposure to unseen, life-threatening hazards with each deployment. They rely on portable, field-ready instrumentation to detect hazards in the harsh battlefield setting without the luxury of a controlled, laboratory environment. The challenge of finding trace levels of hazardous materials in this setting is intensified by the critical size, weight, and power specifications that portable, battlefield instrumentation must meet. This article discusses the evolution and utilization of Raman spectroscopy as it applies to demanding battlefield settings.

Philae Lander Sends First-Ever Images From A Comet
The Philae lander, the first human spacecraft to ever land on a comet, has sent back initial images from the surface. After a touch-and-go landing, the probe settled on the surface of the comet that it has been chasing since 2004.
Miniature Camera Modules For Visualizing Micro Invasive Surgery
The miniaturization of camera modules allows visualization inside the body with ever smaller incisions. These miniature digital camera modules — hardly bigger than a grain of salt — enable novel medical tools, where visualization is possible for the first time and where previous procedures had to be done completely blind. In this article, AWAIBA, a reputed leader in miniature camera modules as small as 500 mm side length, provides an overview of these miniaturized cameras and explores potential new applications for the technology.

4 Electronic Design Requirements Of The System-Integrated Soldier
Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.
The Top 5 Technologies From DSS 2014
With more than 450 companies at this year’s event and only three days to explore, it was an almost overwhelming task to try and take in all of the technology on display. Regardless, I did my best, and here is my list of the top five most exciting technologies I caught at the show.
Ladybug Takes Off In Slow Motion
This particular sequence was recorded with at pco.dimax HD CMOS camera at 3,000 frames-per-second and 1296 x 720 pixel resolution. Once the ladybug unfolds its wings, the display speed is reduced to 25 fps.
Clear, Colored Images Captured In Low Light
This video was taken out of a lab window at dawn. The sequence displays three times at 16bit and 8bit scaling to capture details. All imagery was captured by the pco.edge – a color, sCMOS (scientific CMOS) camera operating at 2560 x 2160 resolution at 100 frames/s.
Fishing Kingfisher in Slow Motion II
The pco.dimax HD is a high-speed, 12-bit CMOS camera ideal for a variety of slow-motion capture applications. In this video example, Rainer Bergomaz from Blue Paw Artists used one of these cameras with 1920 x 1440 pixel resolution @ 1060 frames/s to capture sequences of young kingfishers trying (successfully, in some instances) to catch fish.
Magic Drops In Slow Motion
Blue Paw Artists’ Rainer Bergomaz and Daniel Nimmervoll used the pco.dimax HD high-speed camera to capture water droplet sequences, showing that slow motion imagery is just as appealing aesthetically as it is scientifically.
Tracking Objects Through Heat Signature Acquisition
This video showcases an ATP (acquisition, tracking, and pointing) tracker in action in both day and nighttime conditions. The imagery was captured with DRS Technologies’ infrared cameras. The ATP tracker used in this footage is the result of a Senior Capstone Project in Texas A&M’s electrical engineering program.
PHOTONICS ONLINE SPECIAL FEATURE
Sierra-Olympic’s Vinden CZ is a thermal imaging camera with a 12x zoom factor for 640 x 480 resolution and a 6x zoom factor for 320 x 240. It’s well suited for system integrators in the security and surveillance space, or any other project requiring advanced continuous zoom thermal imaging capabilities.

Cameras for Astronomy: Observations in the H Band
This application note contains sample images of Uranus and the Trapezium cluster, both observed in the astronomical H band (1.625µm).
System Integration Of Fiber Lasers And Its Effects On Laser Quality
Recently, companies that perform system integrations have become more concerned about the quality of the laser delivered to the process and not just the quality of the laser source itself. Some companies are now starting to use beam profiling for much more than simply qualifying the laser source. They also leverage the technology to qualify the components that are integrated into their systems and to characterize the application of the laser. Using sample beam profiles as illustrations, this article defines laser quality and provides examples of how laser system quality can be affected by system componentry.
Liquid Silicone Rubber Takes The Heat
Liquid silicone rubber is created in high heat conditions, and as such, can withstand a variety of high heat applications. This makes LSR ideal for medical devices because of its ability to withstand with high temperatures associated with device sterilization. Its stability also prevents it from affecting skin surfaces, and from skin surfaces affecting it.
Utilizing Inkjet Coating Technology For Optics And Injection Molded Parts
This case study explains how Carclo developed an inexpensive, one-sided, anti-scratch coating resistant to UV light, abrasion, solvents, and chemicals that could be applied to a customer’s optics without having a negative impact on its optical properties.
