Hyperspectral and Remote Sensing the focus at EARSeL!

Posted by Christopher Van Veen on Wed, Apr 03, 2013

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.

EARSeL blog photoHeadwall is seeing a meteoric rise in the use of small and light UAVs for remote sensing activities. SkyJib (from Droidworx) and the Mk II by Winehawk Labs are two such examples, and you’ll see both at EARSeL. The more nimble these hand-launched airframes get, the smaller and lighter the sensors themselves need to be. Headwall’s collaborative engineering approach gives customers a fast path to success with lightweight solutions that also include integrated application software and a GPS/INS. The beauty of Headwall’s Micro Hyperspec sensor is that it is purpose-engineered for flight. Besides being rugged, it also provides outstanding spatial and spectral resolution in the NIR (900nm-1700nm) and VNIR (380nm-1000nm) ranges while also having a very wide field of view. A wide field-of-view means a more efficient the flight path. In other words, the UAVs can cover more territory by collecting precise spectral detail not only directly below but also off to the sides.

While small, hand-launched UAVs are perfect for a wide range of scientific exploration activities, fixed-wing aircraft ranging from the Cessna to the Twin Otter are also used as a platform for hyperspectral sensors. Headwall’s High-Efficiency Hyperspec sensor covers the NIR (900nm - 1700nm) and SWIR   (950nm - 2500nm) spectral ranges. Aberration-corrected and completely athermalized, it provides the highest optical performance and diffraction efficiency of greater than 90%. We’ll be showing this at EARSeL also.

Later in April…beginning on the 3oth actually…Headwall will be at the Defense, Security + Sensing show in Baltimore. We’ll be in Booth 1830 at the Baltimore Convention Center for DSS, which is quickly becoming the go-to show for all things related to surveillance and reconnaissance. While the interest here is largely airborne, visitors also want to know about ground-based and hand-held hyperspectral sensors. Headwall’s flagship hand-held sensor is Hyperspec RECON, which won the R&D100 Award in 2012. This portable instrument covers the VNIR (380nm-1000 nm) spectral range and can render a 6-inch sq. hyperspectral scene at a distance of over a kilometer. Best of all, it’s easy to use and can be ‘tuned’ by loading spectral libraries via an integrated SD slot. Hyperspec RECON represents a very flexible reconnaissance platform that can also be used in a stationary manner (mounted to a mast or a vehicle, for example).

While Hyperspec RECON and its handheld ingenuity is a groundbreaking achievement, many applications need instruments that can either point-and-stare’ or ‘pan-and-tilt.’ Headwall has sensors for both types of deployment that exhibit the very same aberration-corrected concentric imaging performance as their airborne counterparts. Since hyperspectral imaging depends on movement to occur, the instruments are motorized and fully engineered for the tasks they are challenged with.

Headwall will be at several exhibitions and conferences throughout 2013 aside from the two described here. These events will serve as excellent venues as we come out with new products and enhanced versions of existing ones.

Headwall's Hyperpectral Sensors Soar at DSS

Posted by Christopher Van Veen on Thu, Apr 26, 2012

The Defense, Security + Sensing (DSS) show moved from its traditional Orlando venue to Baltimore this year. Flush with technology-driven agencies, the Baltimore-Washington area is a natural magnet for a show such as DSS.

DSS 2012 BaltimoreThe first two days at DSS have been amazing for Headwall, with visitors drawn by the sight of the Insitu 'ScanEagle' UAV. This impressive aircraft is one example of a typical platform that can easily deploy Headwall's 'Micro Hyperspec' hyperspectral sensor. Size, weight, and power-consumption specifications (SWaP) for any payload need to be carefully balanced when it comes to deployment on any mission-critical UAV. So far during the three-day DSS show, the ability to demonstrate our lightweight sensor aboard ScanEagle is proving the point better than any photograph could!

Closer to the ground, Hyperspec RECON is drawing tremendous interest from technologists who need a portable, simple-to-use hyperspectral sensor that can be deployed on the battlefield. Hyperspec RECON can render a 6" x 6" hyperspectral scene at a distance of 1.5 km and process that image data in only a few seconds. Using a spectral library of known signatures, RECON is able to immediately identify them within the field of view. Aberration-corrected imaging technology combined with robust, fast data-processing software give our troops immediate, accurate, and actionable hyperspectral data in the field of battle.

DSS wraps up later today at the Baltimore Convention Center.

Hyperspectral Imaging Heads to Baltimore for DSS!

Posted by Christopher Van Veen on Fri, Apr 20, 2012

DSSDSS--Defense, Security + Sensing--is the world's largest unclassified event for defense, security, and sensing applications for industry and the environment, and we'll be there in Booth 2220 starting Tuesday April 24.

DSS relocated from Orlando to Baltimore for 2012. The move from Orlando is a good one because it will bring in more experts than ever in the fields of homeland security, defense, and environmental sensing. Here, they'll gain visibility for their work and products and receive face-to-face feedback from their peers.

Hyperspec RECON

DSS is a premiere event on the Headwall Photonics show schedule. New this year will be a product called Hyperspec RECON, which is a portable yet rugged hyperspectral sensor that can render a 6" x 6" target at distances of up to 1.5km. We'll have the RECON system on display and operational, so be sure to take a look!

One of the most critical applications for hyperspectral technology in the field of defense, security and sensing is aboard airborne platforms such as the ScanEagle from Insitu. We'll have an actual ScanEagle in our booth, courtesy ofScanEagle by Insitu Insitu, to demonstrate how our lightweight Micro Hyperspec sensors can be deployed in packages where size, weight, and power (SWaP) need to be optimized.

We look forward to seeing you at DSS starting April 24!
