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 请求资金来开发集成仪器包，其中包括能够以高时间和空间分辨率测量光场的所有斯托克斯参数的偏振成像传感器。该仪器包将部署在水下，并将被编程为以规则的时间步长自动记录近地表偏振光场的测量结果，同时在整个立体角上重新定向。这些测量与相关水的固有光学特性的测量和基于蒙特卡罗的辐射传输模型结合使用，预计将有助于加深对与遥感相关的光学辐射传输以及生物所采用的适应机制的理解。更广泛的影响：如果成功，PI 将开发出一种可部署在各种海洋条件下的水下偏振相机。这可能会带来工程、海洋学、生物学、地质学和物理学方面的新发现。该仪器本身也可能会促进生物医学成像领域的进步，其中偏振已显示出巨大的前景。该研究的跨学科性质肯定会吸引大量群体，并且对于所有年龄段的教育推广至关重要。所有三位 PI 都积极参与教育和社区外展计划。
