Headwall Delivers Micro-Hyperspec® Sensors to Columbia University

Posted by Christopher Van Veen on Thu, Oct 09, 2014

High-performance imaging sensors on small, commercial UAS will assess ocean and sea ice variability in Arctic zones

FITCHBURG, MA - OCTOBER 9, 2014: Headwall Photonics has delivered two high-performance hyperspectral imaging sensors to Columbia University as part of its Air-Sea-Ice Physics and Biogeochemistry Experiment (ASIPBEX). ASIPBEX is part of a larger international collaborative investigation of Climate Cryosphere Interaction with colleagues from Spain, Germany and Norway. This crucial remote-sensing project will use a high-endurance unmanned aircraft system (UAS) to investigate climatological changes present in the Arctic Ocean around Svalbard, Norway. The instrument payload comprises two Micro-Hyperpsec sensors; one will cover the Visible-Near-Infrared (VNIR) range of 400-1000nm while the other will cover the Near-Infrared (NIR) range of 900-1700nm. Together, the sensors will be crucial in detecting indicators of sea ice physics, solar warming and global carbon cycles.

Smaller, Lighter, Better: Hyperspectral on UAVs

Posted by Christopher Van Veen on Fri, Aug 08, 2014

At Headwall we've been busy listening to the market. When it comes to airborne remote sensing, the market is telling us that they favor UAVs (unmanned aerial vehicles) of all kinds: fixed-wing, multi-rotor, and so on. There's no end to the number of companies producing UAVs globally. Because many UAVs produced today are very small and affordable they are 'within reach' of those with even modest means. Universities represent one key market where the use of UAVs is rapidly increasing. Full of scientists and research departments, universities around the globe see these small and light UAVs as a perfect platform from which to launch their exploratory studies. They are affordable, easy to assembly and transport, and (especially with multi-rotor models) can take off and land within a very small footprint.

Hyperspectral Takes Wing Over Ontario!

Posted by Christopher Van Veen on Thu, May 01, 2014

Under cloudless skies in Ontario recently, Headwall achieved a very notable milestone: we became the first to fly both hyperspectral and LiDAR aboard a small, fully integrated handheld UAS. The test flights not only verified the reliable airworthiness of the system but also the ability to collect valuable hyperspectral and LiDAR data in real time.

UAVs and Hyperspectral Imaging Unite

Posted by Christopher Van Veen on Tue, Mar 25, 2014

One of the things we’re seeing at Headwall is the proliferation of airborne applications. Multispectral suffers a bit with respect to hyperspectral (a handful of bands versus hundreds), which is why hyperspectral is winning the day.

History Made, History Seen with Hyperspectral Imaging

Posted by David Bannon on Mon, Mar 03, 2014

As the market for hyperspectral sensing technology moves forward and advances, Headwall’s Application Engineering team has been able to gather a rare view into the past through the hyperspectral scanning of some of the most important historical artifacts and papers in the United States. For the first time ever, hyperspectral VNIR and SWIR imaging was conducted on key historical documents from the US Civil War period.

Hyperspectral Sensors for UAV Applications

Posted by Christopher Van Veen on Wed, Feb 19, 2014

The scientific research community is beginning to understand and embrace hyperspectral imaging as a useful tool for a few primary reasons. First, sensors are more affordable than ever. Originally conceived as multi-million-dollar ISR platforms for defense applications, hyperspectral imagers have been successfully ‘commercialized’ over the past few years. Scientists typically embracing RGB or multispectral technology before can now acquire hyperspectral sensors at affordable price points.
