The significant effects of aerosols on public health and climate drive a growing necessity for the characterization of particulate matter in air pollutants. The earth-orbiting Multi-Angle Imager for Aerosols (MAIA) instrument will combine radiance and polarization measurements to derive features of ground-level particulate matter. The optical design requires an in-depth analysis of several key polarization factors in order to meet stringent requirements on radiometric and polarimetric accuracy. A simple two-layer optical coating, a pair of achromatic quarter-wave plates, and analysis of the polarization aberrations are used to minimize the effects of polarization errors and achieve high polarimetric accuracy.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
