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.

国际和平研究所要求提供资金，以开发一套综合仪器，其中包括一个能够以高时间和空间分辨率测量光场所有斯托克斯参数的偏振成像传感器。这套仪器将部署在水下，并将被编程为以规则的时间步长自动记录近表面偏振光场的测量，同时在全立体角度上重新定向。这些测量与相关水的固有光学性质的测量和基于蒙特卡洛的辐射传输建模相结合，有望提高对与遥感相关的光学辐射传输的理解，以及对生物生物所采用的适应机制的理解，以增强它们用于通信的对比度或将它们自己隐藏在偏振光学背景下。广泛的影响：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。这可能会导致工程学、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，在生物医学成像领域，偏振显示出了巨大的前景。这项研究的跨学科性质肯定会吸引大量的群体，对于所有年龄段的教育推广来说都是最好的。所有三个私人助理都积极参与教育和社区外展计划。
