Hyperspectral Sensors

Capture spectral information to identify minerals, vegetation and other materials

Hyperspectral sensors collect hundreds of narrow bands of data along the electromagnetic spectrum. The sensors produce narrow bandwidths (5-10 nm) and secure roughly 100 to 200 spectral bands of data per image pixel. The data is collected as a three-dimensional hyper-cube with x, y and λ values.

Each pixel gets its own spectral profile containing location data, followed by hundreds of digital numbers that align with the corresponding spectral bands.

These sensors can detect and identify minerals, vegetation and other materials that are not identifiable by other sensors. They are used in plant nutrient status, plant disease identification, water quality assessment, foliar chemistry, mineral and surface chemical composition and spectral index research.

Hyperspectral sensors have two methods for scanning: Push Broom and Whisk Broom.

Push Broom scanning, which is ideal for drone use, captures full spectral data simultaneously as the drone moves forward using a line of sensors that runs perpendicular to the drone's flight direction. With this method, the scanner is able to look at a particular area for a longer period of time enabling more light to be gathered.

Manned aerial and satellites use both Whisk Broom and Push Broom scanning. In the Whisk Broom method, a mirror scans the platform's path and light is reflected into a single detector, which collects data one pixel at a time. This method enables wide swaths of ground to be scanned and produces some pixel distortion.
