Hyperspectral Sensors

Headwall’s HYPERSPEC® family of hyperspectral sensors are small, light, and rugged. The simple but elegant all-concentric design uses precisely-engineered master-quality holographic diffraction gratings and mirrors to deliver high signal-to-noise, high spectral and spatial resolution, and a wide, aberration-corrected field of view.
HYPERSPEC® sensors are line-scanning hyperspectral cameras (sometimes called pushbroom) that collect reflected light through an image slit. One row of spatial pixels is collected per frame as motion occurs, with each pixel containing full spectral data. Motion can be accomplished in two ways: either as an airborne deployment (UAV, aircraft, or satellite) or stationary (where motion is accomplished beneath the sensor, such as a food inspection line).  A hyperspectral data cube thus contains complete X, Y, and wavelength data that can be analyzed and managed through powerful applications software e.g. MiniGIS.

Center for Hyperspectral Remote Sensing Europe (CHRSE)

Headwall Photonics Inc., USA and geo-Konzept GmbH, Germany founded the Center for Hyperspectral Remote Sensing Europe (CHRSE) in November 2019.
The CHRSE is located at the headquarters of geo-Konzept GmbH in Adelschlag, Germany. The center will promote the use of hyperspectral data collection in the fields of agriculture, mining, environmental monitoring and infrastructure inspection. The CHRSE has large areas for unmanned drone flights and certified UAV pilots. Demonstrations, tests and training can be carried out on site in a practical manner.

Headwall Nano-Hyperspec (VNIR)

Hyperspectral images increasingly play a role in precision agriculture. Precise and reliable data are necessary for a well-founded decision and an accurate assessment of the plant populations. The classification of plant populations with regard to disease pressure, water shortage and nutritional status and in general plant physiology is put on a broader basis.
The use of concentric mirrors and sophisticated diffraction gratings reduces unwanted interference. The result is a high spatial and spectral resolution. The particularly wide field of vision enables very efficient trajectories when flying. Due to the light, compact and robust design of the sensor, transport and assembly are particularly easy.
In parallel to hyperspectral imaging, Headwall offers the first integrated platform with LiDAR system (Light Detection And Ranging) on ​​a lightweight drone including data-fusion capability. Point clouds can be combined with hyperspectral information about the scanned area and used to create high-resolution digital elevation models (DEM) to benefit higher-accuracy orthorectification.

 

Your benefits

Use in UAV systems is very easy
Comprehensive and detailed assessment of plant stands
High flexibility to modular structure
Typical areas of application: in the air (aircraft, UAV),as part of a benchtop scanning kit, or on a stable position on the ground (rotation platform)

Headwall Micro-Hyperspec (SWIR)

Hyperspectral image sensors enable unique efficiency gains in mining and quarries. Raw material can be analyzed for mineral components early in the production process. Hyperspectral cameras are perfect for installation in linear production processes due to the very high processing speed.

Furthermore, the use of Headwalls Micro-Hyperspec sensors on UAVs is particularly useful in difficult-to-access areas. Compact dimensions, low weight, a high signal-to-noise ratio and a particularly wide field of view are the characteristic features of these airborne-capable sensors. These benefit UAVs by maximizing payload efficiency and allowing greater area coverage during data collection. Headwall’s hyperspectral sensors are also characterized by distortion-correcting optics that lead to higher accuracy.

Headwall Co-Aligned VNIR-SWIR

The Co-Aligned VNIR – SWIR camera system combines the two spectral channels VNIR (visible to near infrared) and SWIR (shortwavelength-infrared) to form a light-weight, compact sensor system for a wide range of applications. Headwall’s precise hyperspectral sensors are based on aberration-corrected optics. This enables a high signal-to-noise ratio (SNR) with the best spatial and spectral resolution and a very large field of view. The VNIR wavelength range can be used to assess plant growth. The SWIR wavelength range is ideal for controlling an investigation area and performing geological material tests.
The Co-Aligned VNIR-SWIR sensor is designed for ground or aircraft based measurements. For measurements on the ground, the sensor is attached to a swiveling stand.
In parallel to hyperspectral imaging, Headwall offers the first integrated platform with LiDAR system (Light Detection And Ranging) on ​​a light weight drone including data-fusion capability. Point clouds can be combined with hyperspectral information about the scanned area and used to create high-resolution digital elevation models (DEM) to benefit higher-accuracy orthorectification.
Other fields of application: testing of asphalt degradation, corrosion of various polymers, oxidation of ferrous metals, condition of coatings, spreading of vegetation, water seepage, excessive moisture…

Headwall Hyperspektral UAV Komplettsystem

Headwall Photonics Inc. is one of the world’s leading manufacturers of hyperspectral sensors. The compact and lightweight design of the sensors enables, among other things also the use of hyperspectral sensors on UAV (Unmanned Aerial Vehicle) systems. Headwall is the only manufacturer worldwide that has integrated a hyperspectral line scanner using their own master-quality holographic gratings on a UAV system in the <25kg category as a complete system. This enables flexible and independent hyperspectral data acquisition without a specialized UAV individual ascent permit. The complete system includes all the necessary hardware and software components so that you can independently carry out a hyperspectral UAV mission flight and the subsequent data preparation and processing. The data remains in your hand during the entire processing (no transfer to an online service). All required software components work offline on your PC.
As a flying hyperspectral sensor, we can currently offer you the Nano-Hyperspec VNIR or the Co-Aligned VNIR-SWIR sensor system. The two systems are characterized by a modular structure and are available in different GNSS accuracies or with a LiDAR system.

Youir Benefits

— Flexible and independent hyperspectral data acquisition
— Complete system, including all necessary hardware and software components & training
— Modular structure of GNSS accuracy and LiDAR
— the data remains in your hand (offline data processing)
