Abstract

As the number of recognized applications for and acceptance of spectral imaging increases, the need for field spectral measurements also increases. The goal of this paper is to help ensure the quality and accuracy of field spectral measurements. Unlike laboratory measurements, where everything is controlled to meticulous detail, field measurements tend to suffer from an almost complete lack of control. Hence, assuring data quality of field measurements can be difficult. To help compensate for some of the problems that arise due to this lack of control, collection protocols are established. Even using collection protocols, sensor artifacts are not always apparent. In this paper, some of these sensor artifacts are presented and discussed. While this paper concentrates on a specific spectrometer, many of the issues, protocols and processing procedures should be generally applicable to most field spectrometers operating in this spectral region.
