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的要求资金开发了一个集成的仪器包，包括一个偏光成像传感器，能够用高时间和空间分辨率测量光场的所有Stokes参数。该仪器包将在水下部署，并将被编程以在常规时步中自动记录近距离极化光场的测量，同时在整个实体角度重新定位。这些测量值与对相关水的固有光学特性和基于蒙特卡洛的辐射转移建模的测量相结合，预计将导致对与遥感的光辐射转移的理解增强，以及与遥感相关的适应机制，以及由生物学生物所采取的适应机制，以增强其对沟通的影响，以增强其对比的对比。可以在各种海洋条件下部署的水下极化相机。这可能会导致工程，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，在这些成像中极化表现出了巨大的希望。该研究的跨学科性质肯定会吸引大量群体，并且是所有年龄段的教育外展的主要范围。这三个PI都积极从事教育和社区外展计划。
