Airborne sensors covers broad spectral range of 400-2500nm

Headwall has released the Hyperspec® VNIR-SWIR sensor for general availability. The high-performance airborne sensor is versatile and covers the broad 400-2500nm spectral range. Precise, high-resolution imaging is achieved through co-registered pixels utilising a single fore-optic input for outstanding spectral fidelity across the entire spectral range.

Designed for remote sensing applications such as environmental monitoring and mineral exploration, the sensor is optimised for size, weight, and reduced power consumption. With a weight less than 30 pounds and a small form factor package (approximately 15" x 15" x 8"), the sensor is designed for use aboard a wide range of airborne platforms. Adding to high image quality is the sensor's very wide field of view and high signal-to-noise (SNR) performance. Headwall has accomplished this by combining the high diffraction ef­ficiency for the VNIR and SWIR spectral regions coupled with very high quantum efficiency of the electronic subsystems.

Pixel co-registration plus aberration-cor­rected optics yields very high spectral and spatial resolution with repeatable measurement accuracy - unparalleled in the industry. With diffractive optics spe­cifically designed and manufactured by Headwall, the patented hyperspectral sensor eliminates image aberrations such as keystone, smile, or stray light and thermal variation that is typically observed with transmissive-based sensors containing prisms and gratings.

"Our remote-sensing customers often need to cover both the VNIR and SWIR spectral ranges but until now, there has not been a hyperspectral sensor capable of reliably providing both VNIR & SWIR data," said Headwall CEO David Bannon. "We developed this co-boresighted and co-registered VNIR-SWIR sensor to avoid the complexities of multi-sensor deployments while keeping the sensor size, weight, and power consumption very low."

Headwall's Hyperspec VNIR-SWIR sensor is also sold with a complete airborne configuration including GPS/INS, high-speed processor and storage, and airborne Hyperspec III software for sensor control and data acquisition.

Headwall's VNIR-SWIR sensor is available for delivery approximately 8 weeks after receipt of order. Headwall's application engineering team is available to assist customers with airborne integration and training.
