Polarization Measurement Errors Due to Spatial and Temporal Misregistration

摘要

This paper focuses on potential false conclusions regarding polarization parameters obtained through the use of a digital camera. It outlines a methodology for calibrating, displaying and visualizing polarization profiles of natural, daylight scenes using a cars (commercial-off-the-shelf) digital camera. It presents cause and effect scenarios related to spatial and temporal misregistration of polarization data and the acquisition of accurate polarization parameters, such as the degree of polarization and the polarization azimuth and ellipticity angles. Trade-offs between precise spatial registration and precise temporal registration are discussed.
