Abstract

The spectrometer is a high spectral resolution instrument which has two sensing heads called cameras. The two cameras were observed to be misregistered relative to one another by up to 6 nm. The cameras were brought to a common wavelength base to correctly compare the data when the two cameras are used in a near-simultaneous mode. The wavelengths were assigned to the respective corresponding camera spectral wavelength bands and spectral bandwidths and sampling intervals calculated for each camera. Spectral bandwidths were larger than expected, but the sampling intervals were in close agreement with manufacturer specifications. Both cameras were calibrated for radiance and irradiance. -from Authors
