Dartmouth Researchers Test First 'Smart Spaces' Using Light To Send Data
One of the problems in the high-tech field of visible light communication (VLC) - or using light to send data wirelessly - is decidedly low tech: The data transmission stops whenever the light is blocked by people's movements, shadows or other obstacles.
Creating Bright X-Ray Pulses In The Laser Lab
X-rays are widely used in medicine and in materials science. To take a picture of a broken bone, it is enough to create a continuous flux of X-ray photons, but in order to study time-dependent phenomena on very short timescales, short X-ray pulses are required. One possibility to create short hard X-ray pulses is hitting a metal target with laser pulses.

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.
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.
Thermal Display Systems For Communications, Tracking, And Scientific Research
This video is an entry from the 2014 DRS Technologies Student Infrared Imaging Competition in which a student designed, constructed, and tested a thermal display capable of showing moving images, text, and patterns.
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.

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.
Advances In sCMOS Camera Technology Benefit Bio Research
Since the inception of digital microscopy, scientific-grade CCD cameras have been the gold standard for imaging due to their sensitivity, linear response to light, and low noise characteristics. However, many cell mechanisms occur on short time scales and emit low luminescence signals, making imaging difficult for slower CCD cameras. This technical note discusses why scientific CMOS (sCMOS) is becoming the sensor technology of choice for live cell fluorescence applications, largely due to their combination of very low electronic noise, high frame rates, and a large field of view.
“NanoFlares” Illuminate Individual Cancer Cells
Recently, a team from Northwestern University developed nanoparticles with a built-in fluorescent tag that are capable of identifying genetic biomarkers specific to cancer. Deemed “NanoFlares,” these particles operate inside the cell and can identify cancer cells in the bloodstream, potentially providing an early warning of metastasis.
Dual-Action Nanoparticle Allows Fluorescence Imaging And MRI
A hybrid nanoparticle has been developed that is compatible with both fluorescence imaging and magnetic resonance imaging (MRI). The new agent may allow a better real-time understanding of tumor biochemistry and drug delivery.
