Wide-angle interference-polarization filter of a video spectroradiometer-gas viewer for recording nitrogen dioxide

摘要

This paper discusses a wide-angle interference-polarization filter that constitutes part of a spectral filtering system based oil the combined use of interference-polarization and narrow-band interference filters, constituting a new type of video spectroradiorneter, intended for monitoring the spatial distribution pattern of the anthropogenic gas NO2 in the near-earth atmosphere.
