Featured Article
High-Speed Imaging Techniques For The Aerospace Industry
 
By Photron, Inc.

Digital image correlation, particle image velocimetry, and schlieren imaging provide engineers in the aerospace industry with insight into the strength and durability of materials, the characteristics of engine combustion processes, the aerodynamics of objects in flight, and much more.

Spotlight On Hyperspectral Imaging
Hyperspectral Imaging Improves Surface Mine Mapping Processes
Article | By Stéphane Boubanga, TELOPS

Traditional methods of mapping surface mines have inherent challenges to obtaining data with enough detail to allow effective tactical and strategic decision making. Hyperspectral infrared imaging eliminates the problems.

Short-Wave Infrared Temporal Multiplexing For Cost-Effective Multispectral Solutions
Application Note | By Michael Stelzl, Xenics

Temporal multiplexing is an alternative approach to hyperspectral imaging that uses a fast LED technology. Instead of broadband illuminating and diffracting the spectrum of light in the camera, a broadband sensitive chip is used, and the illumination spectrum is varied over time via fast triggering.

Aerial Hyperspectral Imaging: OCI Hyperspectral Imagers
Application Note | By Owen Wu, BaySpec Inc.

BaySpec’s OCI-UAV hyperspectral imagers are designed for use on small UAVs to monitor the details of spatial, temporal, and spectral representation of ground objects. This application note discusses benefits that these imagers offer and delivers example images for multiple topography analysis.

Lens Manufacturers: Do You Know The Best Test For Lens Performance?
Article | By Kevin Urben, Image Science Ltd

A high-quality lens begins with a good design, tolerant to small manufacturing errors. The manufacturing process must be tightly controlled, from individual lens elements to final assembly. But, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is necessary.

Medtech Startup Smells Success With Additive Manufacturing
Article | Protolabs, Inc.

Combining the sense of smell with rapidly evolving virtual reality (VR) technology — enabling medical applications including helping soldiers with post-traumatic stress disorder (PTSD)— is the mission of OVR Technology, a startup in Burlington, VT.

FLIR Thermal Datasets For Algorithm Training
Application Note | FLIR Systems, Inc - OEM Cores and Components

The FLIR starter thermal datasets enable developers to start training convolutional neural networks (CNN), empowering the automotive community to create the next generation of safer and more efficient ADAS and driverless vehicle systems using cost-effective thermal cameras from FLIR.

Finished Infrared Optics
White Paper | PG & O Precision Glass & Optics

PG & O finished infrared (IR) optics are designed for a range of applications, including biomedical, industrial, military/defense, homeland security, surveillance, and more. These optics operate from 0.75 µm, the near-infrared (NIR), out to 15 µm, the longwave-infrared (LWIR) spectrum.

Building A Do-It-Yourself Atomic Force Microscope
Article | By James F. MacKay, Mad City Labs, Inc.

Atomic force microscopes (AFMs) are versatile tools for characterizing surfaces down to the subnanometer scale. Researchers can build their own AFMs for as little as $30,000 using off-the-shelf components such as nanopositioning stages.
