Calibration of FUBISS: Free University Berlin's Integrated Spectrographic System

摘要

The new airborne remote sensing instrument FUBISS measures light intensities from the ultraviolet (200nm) to the near infrared (1,7 um) region of the electromagnetic spectrum with a spectral resolution of up to 2,4 nm in the visible and 10 nm in the near infrared range. A number of parameters have a large influence on the measured spectral data of a discrete spectral light curve and must be corrected. We will present a correction and calibration procedure after a short description of the instrument itself. This is followed by a description of the laboratory measurements and the calculation of the offset and calibration coefficients, finally yielding absolute calibrated spectra with an estimated relative error below 1% for a well-known calibration source.
