Today, recon is dominated by unmanned aerial vehicles (UAVs), a much more cost-effective approach that presents no risk to the operators. Of course, imagery is only useful if it’s crisp and clear, which requires both focusing and stabilization. This case study describes the development of a 700-gram gyro-feedback-stabilized sensor turret, which keeps a UAV sensor payload and its electronics steady and aimed while countering vibration, thermal loading, wind forces, and more.

The Advantages Of Piezo-Based Scanning Systems For High-Performance Microscopes
Classical microscopic methods are no longer sufficient in terms of optical resolution or information content. To obtain more extensive and accurate measurement data of a sample, it is now possible to combine different microscopic methods. Combining those methods, however, is very demanding on the positioning system. This article outlines the advantages of using piezo-based scanning stages to ensure image position resolution and accuracy.

Laser physicists have built a tractor beam that can repel and attract objects, using a hollow laser beam that is bright around the edges and dark in its centre.
Designing Athermal Lenses For Long-Wave Infrared Systems
Due to advances in material and manufacturing technologies, the vast majority of lenses used on long-wave infrared (LWIR) cameras are simple: One- or two- element designs with an emphasis on low-cost manufacturing. One effect of this is that most of these cameras are supplied without any means for the user to focus them. This means that the lens must stay in focus over a broad range of temperatures. Since the standard temperatures range for use outdoors is -40°C (really cold) to +85°C (much too hot!), this can provide some interesting design challenges.
These new OEM cameras from Hamamatsu feature an advanced scientific CMOS (sCMOS) image sensor capable of high resolution, fast frame rates, and low noise simultaneously. With their small size, board-level design, and simple, low-cost integration, these OEM cameras are ideal for imaging in life science, failure analysis, and semiconductor inspection.

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

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.
