![]() This allows the direct measurement of all system effects, in contrast with fitting modeled calibration parameters to measured data. With this method, however, linear combinations of Stokes vectors are used to generate highly accurate input states. The proposed calibration method involves the familiar calculation of the polarimetric data reduction matrix by measuring the polarimeter's response to a set of input Stokes vectors. The calibration procedure has been used on infrared and visible polarimetric imagers over a six year period, and resulting imagery has been presented previously at conferences and workshops. Both the calibration and verification methods presented here are performed easily with common polarimetric equipment, and are applicable to visible and infrared systems with either partial Stokes or full Stokes sensitivity. This paper seeks to facilitate discussions within the community on arriving at such standards. It is desirable to develop a standard calibration method, including verification reporting, in order to increase credibility with customers and foster communication and understanding within the polarimetric community. Spradley, Kevin D.Īccurate calibration of polarimetric sensors is critical to reducing and analyzing phenomenology data, producing uniform polarimetric imagery for deployable sensors, and ensuring predictable performance of polarimetric algorithms. ![]() ![]() A proposed standard method for polarimetric calibration and calibration verification ![]()
