The PI's request funding to develop an integrated instrument package including a polarized imaging sensor capable of measuring all Stokes parameters of the optical field with high temporal and spatial resolution. This instrument package will be deployed underwater and will be programmed to automatically record measurements of the near-surface polarized optical field at regular time-steps while re-orienting over the full solid angle. These measurements, used in combination with measurements of the associated water's Inherent Optical Properties and Monte Carlo based radiative-transfer modeling, are expected to lead to enhanced understanding both of optical radiative transfer relevant to remote sensing, and also of the adaptation mechanisms employed by biological organisms, either to enhance their contrast for communication or to conceal themselves against the polarized optical background.Broader Impacts: If successful, the PIs will have developed an underwater polarimetric camera that can be deployed in variety of ocean conditions. This could lead to new discoveries in engineering, oceanography, biology, geology, and physics. The instrument itself may also lead to advancements in biomedical imaging, where polarization has shown significant promise. The interdisciplinary nature of the research will certainly appeal to a large number of groups, and is prime for educational outreach for all age groups. All three PIs are actively engaged in educational and community outreach programs.

PI的要求资金开发一个集成的仪器包，包括一个偏振成像传感器，能够测量所有的斯托克斯参数的光场具有高的时间和空间分辨率。该仪器包将部署在水下，并将被编程为自动记录测量的近表面偏振光场在定期的时间步长，同时重新定向在整个立体角。这些测量，与相关的水的固有光学特性的测量和基于蒙特卡罗的辐射传输建模相结合，预计将导致提高对与遥感相关的光学辐射传输以及生物有机体所采用的适应机制的理解，或者是为了增强它们的对比度以便进行通信，或者是为了在偏振的光学背景下隐藏它们自己。 如果成功，PI将开发出一种可以在各种海洋条件下部署的水下偏振相机。这可能导致工程学、海洋学、生物学、地质学和物理学的新发现。该仪器本身也可能导致生物医学成像的进步，其中偏振显示出显着的希望。研究的跨学科性质肯定会吸引大量的群体，并为所有年龄组的教育推广提供了首要条件。所有三个PI都积极参与教育和社区外展计划。
