Hyperspectral sensor

Headwall Photonics

Headwall Photonics will have its Nano-Hyperspec hyperspectral sensor on display at SPIE Photonics West 7-12 February in San Francisco.

The Nano-Hyperspec sensor operates in the VNIR (400-1000nm) spectral range and is designed for use in small, hand-launched unmanned aerial vehicles (UAV). It features a 640 x 480 CMOS image sensor with a 7.4 µm pixel size that achieves frame rates up to 480 fps.

In addition, the Nano-Hyperspec also features onboard data processing and storage and has 640 spatial bands and 270 spectral bands at a resolution of 2-3 nm.

The sensor has a GigE interface, a 17 mm lens, a 15.9° field of view, and a storage capacity of 480GB. Nano-Hyperspec sensors are suitable for use in UAV applications, including environmental monitoring or agricultural tasks.

Headwall's hyperspectral sensors are all based on a patented, concentric, aberration-corrected design using precision high-performance gratings. This fundamentally simple yet elegant design is very robust and features no moving parts and no transmissive optics such as prisms that contribute to measurement inaccuracy and stray light.

Headwall's sensor design provides high signal-to-noise and outstanding spatial and spectral resolution across the entire spectral range and field of view. The very wide field-of-view of Nano-Hyperspec is crucial for airborne applications that demand flight-path efficiency.
