Kurzfassung
We show the signal dependent non-linearity calibration of a HySpex VNIR-1600 hyperspectral sensor using the light addition method. The method has the advantage that a wide spectral range can be calibrated simultaneously with high accuracy. We developed a new setup that uses two lamps, which are coupled into an integrating sphere. The setup can illuminate the whole field of view simultaneously. Additionally, we enhanced the method to allow a denser sampling of the calibration curve than conventionally possible. The results show non-linearities up to 15% dependent on the detector area. After correction, the remaining error is negligible.
