The PI's request funding to develop an innovative light-field sensing instrument package that will enable dynamic characterization of the spatial, spectral, temporal, and polarization aspects of light in aquatic and other moist environments. This instrumentation will be small, portable and waterproof so that it can be readily deployed (e.g. by a SCUBA diver) in the exact natural habitats and time frames in which animals are interacting and light is changing. A new state-of-the-art Hyper-Spectral Imager (HSI) with rapid image exposure times and appropriate light sensitivity will be combined with a unique Multi- Channel-Spectro-Polarimeter (MCSP) that complements the HSI by rapidly measuring the downwelling and sidewelling light fields at the time of imaging. Light plays a key role in many biotic and abiotic systems on earth. Animal and plant light-sensing systems use different aspects of light for numerous functions. This novel instrumentation set will provide a revolutionary capability of simultaneously acquiring detailed imagery and light-field data adaptable to many scientific endeavors. Here we focus our testing on dynamically behaving organisms (e.g. cephalopods and marine fishes) during visual communication and camouflage under changing light fields, but the instrumentation will be equally functional for studying static aquatic scenes (i.e., corals, seagrass) or a wide range of animals (birds, insects, amphibians, reptiles, etc.) in high-humidity terrestrial environments such as rain forests.Broader Impacts: The utility of the instrument proposed is without question. It would revolutionize the discipline of visual ecology and behavior. The technology limits what we can do today and these applicants believe they have designed a hyperspectral video imager and multichannel polarimeter that combines the best of both to give the investigator an unprecedented array of light information about visual scenes. The PI's are pushing all the right boundaries and that such an instrument will have broad applicability and appeal.

PI的请求资金以开发创新的光场传感仪器包，该仪表套件将在水生和其他潮湿环境中对光的空间，光谱，时间和极化方面进行动态表征。该仪器将很小，便携式和防水性，因此可以在动物相互作用和光线变化的确切自然栖息地和时间范围内容易部署（例如，通过水肺潜水员）。具有快速图像曝光时间和适当的光灵敏度的新的最先进的高光谱成像仪（HSI）将与独特的多通道光谱极偏振仪（MCSP）结合使用，该仪表在成像时通过快速测量下降的和侧面的光场来补充HSI。光在地球上许多生物和非生物系统中起着关键作用。动物和植物的光感应系统使用光的不同方面用于众多功能。这个新颖的仪器集将提供革命性的能力，即同时获取详细的图像和适应许多科学努力的光场数据。在这里，我们将测试重点放在视觉传播和伪装过程中动态行为的生物（例如头足动物和海洋鱼类），但仪器将同样有效，可用于研究静态的水生风景（即珊瑚，海格，海格）或广泛的动物（鸟类，昆虫，昆虫，海洋，众多的环境），例如，林中的环境等范围很广）。影响：毫无疑问，提出的工具的实用性是毫无疑问的。它将彻底改变视觉生态学和行为的纪律。这些技术限制了我们今天能做的事情，这些申请人认为他们设计了一个高光谱的视频成像仪和多通道偏光仪，它结合了两者的最佳人选，以使研究人员提供有关视觉场景的前所未有的轻度信息。 PI正在推动所有正确的界限，这种工具将具有广泛的适用性和吸引力。
