Abstract
Hyperspectral imaging cameras must be characterized and calibrated prior to data collection. Efforts are underway to standardize the protocols to characterize and calibrate these systems. The goal of this research is to create an approach using the existing NVLabCAP software produced by the NVESD Advanced Sensors Evaluation Facility (ASEF) to aid in characterizing and calibrating specifically visible near-infrared (VNIR) pushbroom style hyperspectral imagers. NVLabCAP has been established as the standard for characterizing and calibrating electro-optical (EO) and infrared (IR) sensors for the Department of Defense and concepts used for EO/IR sensors can be carried over to hyperspectral systems. This paper will cover the theory behind the hyperspectral imager used, valid methods of characterizing VNIR pushbroom imagers, what methods from NVLabCAP can be used for this purpose, and the transformations needed to fit the data into a structure NVLabCAP can utilize.
