Summary

Hyperspectral imagery (HSI) microscopy allows for vegetation and geologic material to be examined at the sub-centimeter spatial scale.

Description

hyperspectral imager

NIST has developed a laboratory dedicated to measuring the optical properties of materials through the use of commercial and custom hyperspectral imagers. The custom built hyperspectral imaging microscope covers the 400 nm to 2500 nm spectral range using narrow contiguous spectral bands. This system provides a means to collect >10,000s of spectra from both pure substances and mixtures. The large abundance of spectra allows for a more detailed understanding of the distribution and variability of spectra. This additional information may aid in understanding the variability observed in ground truth spectra collected from portable spectrometers. Additionally, the datacubes collected can serve as proxies for airborne and spaceborne collected datasets for test and evaluation purposes.
