Spotlight On Environmental Sensing
Understanding Turbulent Flows

Learn how the simultaneous application of PIV and PLIF measurement techniques sheds light on turbulent entrainment, a process that has implications for oil spills, wind farms, and more.

SWIR Images Monitor Air Quality From Space

Flying a Sensors Unlimited 640HSX InGaAs SWIR camera, the GHGSat’s microSat circles the Earth every 90 minutes collecting infrared images. Data from the microSat will enable industries to monitor and quantify their own carbon dioxide and methane emissions to better manage and reduce their impact on air quality.

Spectroscopic Materials Analysis In The Palm Of Your Hand

Handheld optical spectroscopy’s newest tool features an expanded wavelength detection range, tougher packaging, and the power to streamline countless recycling, food, and industrial applications.

Scattered For Safety — Diffused Light Prevents Danger

Residential fires are among the most feared dangers of everyday life, with homeowners often covering financial risks with fire insurance and having a fire extinguisher ready. As part of a smart home, smoke detectors could be controlled with a mobile device, to allow homeowners to react to dangerous situations, even from miles away.

Industry Insights
LIDAR – Lasers Rule For Remote Distance Measurement

Autonomous vehicles, military ranging, atmospheric sensing, and traffic monitoring are just some of the applications for this versatile technique.

Volcanic Eruption Observations From An Elevated Point Of Stromboli Using Thermal Infrared Hyperspectral Imaging

Research on different indicators of imminent volcanic eruptions is carried out on an ongoing basis, especially with volcanoes located close to urban areas. This application note highlights the benefits of using standoff infrared hyperspectral imaging for characterizing volcanic process.

Foreign Object Detection In Food Inspection And Sorting

Food inspection, in connection with automated sorting and classification methods, has become a major field of application for advanced image capture systems and infrared cameras. This case study tells how Xenics' line scan SWIR camera Lynx is used for complex imaging tasks.

Specialized Thin Film Optical Mirrors Enable VIRUS Spectrograph System In Dark Energy Experiment

PG&O designed and delivered specialized optical mirrors to Texas A&M University and the University of Texas at Austin for use in building the first-of-its-kind VIRUS (Visible Integral-field Replicable Unit Spectrograph) instrument, a key part of the Hobby-Eberly Telescope Dark Energy Experiment, or HETDEX.
