Collaborative Research: Development of a high-resolution real-time polarization image sensor for marine deployment

PI申请资金用于开发一个集成仪器包，包括一个偏振成像传感器，能够以高时间和空间分辨率测量光场的所有Stokes参数。该仪器包将部署在水下，并将被编程为自动记录近表面偏振光场的测量，以规则的时间步长，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测量和基于蒙特卡罗的辐射传输建模相结合，有望增进对与遥感相关的光辐射传输的理解，以及对生物有机体采用的适应机制的理解，这些机制要么增强其通信对比度，要么在偏振光学背景下隐藏自己。更广泛的影响：如果成功，ppi将开发出一种水下偏振相机，可以部署在各种海洋条件下。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。仪器本身也可能导致生物医学成像的进步，其中偏振已显示出重大的希望。这项研究的跨学科性质肯定会吸引大量的群体，并且是所有年龄组的教育推广的主要内容。这三个pi都积极参与教育和社区外展计划。

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.
