Nano-Hyperspec...in the air and on the ground

Next week during Photonics West we’ll be demonstrating our very newest hyperspectral sensor: Nano-Hyperspec. We gave it that name because it’s small...exceptionally small. Think of a Rubik's Cube and you've got it. The market said it needed a robust, aberration-corrected hyperspectral sensor purpose-built for small, hand-launched UAVs. One perfect example is the X6 from the Aibotix division of Leica-Geosystems, a company with whom Headwall signed an agreement in late 2014. “There’s a confluence within the remote sensing marketplace,” said Headwall CEO David Bannon. “The attractiveness of affordable, easy to launch UAVs runs headlong into the need for perfectly matched sensor instruments that they can carry.” In conceiving Nano-Hyperspec, Headwall consolidated and integrated as much as possible to yield a small, performance-packed unit that even the smallest UAVs could easily carry.

Headwall Delivers Micro-Hyperspec® Sensors to Columbia University

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

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!

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

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.

Hyperspectral Sensors for UAV Applications

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.

Headwall Remote Sensing Capabilities Seen “Down Under”

This past week, Headwall remote sensing team finished a productive week Down Under at the International Geoscience and Remote Sensing Symposium (IGARSS) in Melbourne, Australia.  The conference, organized by the IEEE, comprises a ‘Who’s Who’ across the global remote sensing community. But curiously absent were representatives from the United States, probably reflecting the topic du jour: sequestration. Imagine holding a geo-spatial and remote sensing conference and no one from NASA was able to attend?

Hyperspectral and Remote Sensing the focus at EARSeL!

Headwall's exhibition schedule kicks into high gear this month. First up is our appearance at the 8th Imaging Spectrometry Workshop, sponsored by The European Association of Remote Sensing Laboratories (EARSeL). This event gives visitors the opportunity to understand how hyperspectral imaging can be a valuable scientific tool for the research community. Precision agriculture, mining & minerals, petroleum pipeline surveillance, and disaster mitigation are just a few application areas and more are uncovered all the time as the technology becomes more affordable and easier to use.

Resource Exploration Using Hyperspectral Imaging

Headwall utilizes hyperspectral sensing technology as an essential industrial inspection platform and has made this technology increasingly valuable across a wider spectrum of commercial applications and most notably in the oil & gas industry.  Companies in the petro-chemical industry focus much of their financial capital and effort on efficient pipeline distribution, refinery operations, and environmental monitoring.  Not only for exploration, but also to keep to keep their refining and distribution infrastructure safe.
