With a hyperspectral camera, you're looking at the actual material that something is made of.
In addition to these conventional sorting methods, the Nimbus is able to sort based on biological characteristics, such as chlorophyll (Fluo ™), mycotoxins (Detox ™), water (SWIR), and can be equipped
with a hyperspectral camera to identify the material's unique fingerprint.

But when prospecting for new finds, they're more likely to use tools such as
hyperspectral imagery, which can find electromagnetic fingerprints of objects and land features invisible to the naked eye, or light detection and ranging (LIDAR) technology, which maps subtle surface variations
with extreme accuracy.
There are only a handful of other researchers in the world using
hyperspectral imaging in combination
with other non-destructive and micro-destructive techniques to understand how a work of art is made, Walton said.
Together
with micro-samples extracted from strategic locations, the XRF results, along
with further images generated by Delaney from the
hyperspectral reflectance, reveal the steps of creation taken by Picasso.
They are currently developing a spectral library for different weeds using the high - end
hyperspectral spectroradiometer available
with Rajan.
With cross-calibrations,
hyperspectral IR measurements have been used for quality control for other sensors (including MODIS).
They're familiar
with a range of visual system hardware, such as a structured - light 3D scanner, a
hyperspectral imager and LIDAR (Light Imaging, Detection and Ranging).
