Calibration algorithms for an imaging spectrometer


APEX team; Dell'Endice, F; Schaepman, Michael E (2009). Calibration algorithms for an imaging spectrometer. In: 2009 IEEE International Geoscience and Remote Sensing Symposium (IGARSS 2009), Cape Town, South Africa, 12 July 2009 - 17 July 2009, II 81 -II 84.

Abstract

This paper presents a software calibration/characterization
utility aimed to automatically perform the laboratory
calibration of an imaging spectrometer. Quantitative remote
sensing algorithms requires well-documented instrument
optical performances along with characterization of nonuniformities as, for instance, smile and keystone. Automatic calibration data acquisition and processing facilitate the understanding of the instrument properties and allow the implementation of specific correction schemes. The concept of calibration cube is also introduced as a promptly accessible data structure for the retrieval of optical properties in any detector position. A case study along with all its relevant results is also introduced, based on the Airborne Prism Experiment (APEX) imaging spectrometer. Recommendations and suggestions are also given for customized implementations of this tool.
