Polarization information is abundant in nature, including the underwater environment. Polarization of light in the underwater environment is due to light coming from both the sun and from the sky. Hence, the underwater polarization is primarily determined by light’s transmission from air to water and in-water scattering. In this talk, we will present a new framework to solve sun’s position (heading and elevation) using background underwater polarization information. Based on this data, the underwater geo location of an observer can be determined passively. Extensive experimental data will be presented in the talk to demonstrate the accuracy of this method.

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.
