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.
