Abstract
Hyperspectral imagers provide spectral reflectance values representative of the material being observed. Methods to evaluate uncertainties of hyperspectral imagers remains elusive. All spectrometers are subject to uncertainties attributed to various factors such as wavelength, spectral bandwidth, and linearity. Measuring a set of color tile standards with a variety of known spectral reflectance curves provides a means to quantify the differences between the measured and the known reference values. In effect, this takes a bulk of the uncertainty factors into account. Here we report on the development and application of this method to reduce the measurement errors.
