Abstract

The upcoming IEEE standard P4001 outlines a set of parameters for characterizing the performance of hyperspectral cameras along with recommended measurement procedures. This study concentrates on validating a simplified approach to measure the across-track spatial resolution of a pushbroom hyperspectral camera with a sensor sampling factor of two or higher, in comparison to the scanning-based approach described in the standard. The findings indicate that the snapshot-based method produces values for the width of the sampling line spread function in the across-track direction that closely match those obtained through scanning with sub-pixel steps for hyperspectral cameras with a sensor sampling factor of two or higher.
