 DESCRIPTION (provided by applicant): We are proposing to develop the polarized light field microscope for analyzing the architectural dynamics inside living cells, tissues and cell-free model systems. The instrument combines comprehensive polarization analysis and 3D imaging of microscopic specimens in a single snapshot using the new approach of light field imaging. The project includes the development of the hardware, software and algorithms required for capturing polarized light field images and their tomographic reconstruction into 3-dimensional maps of birefringence, diattenuation and polarized fluorescence. The instrument development is guided by several application projects including the remodeling of the extracellular collagen matrix by fibroblast cells, the spatial coordination in the assembly of higher order septin structures inside eukaryotic cells and the origins of chromosome malorientations and their repair in the meiotic spindle of spermatocytes. Information about the technology, including software components and instrument design that are developed under this grant, will be made available for users and developers on an established web portal called OpenPolScope.org.

 描述（由申请人提供）：我们提议开发偏振光场显微镜，用于分析活细胞、组织和无细胞模型系统内部的结构动力学。该仪器使用光场成像的新方法，将全面的偏振分析和显微样本的 3D 成像结合在单个快照中。该项目包括开发捕获偏振光场图像所需的硬件、软件和算法，并将其断层重建为双折射、衰减和偏振荧光的 3 维图。该仪器的开发以多个应用项目为指导，包括成纤维细胞对细胞外胶原基质的重塑、真核细胞内高级隔膜结构组装的空间协调以及染色体定向不良的起源及其在精母细胞减数分裂纺锤体中的修复。有关该技术的信息，包括根据这笔拨款开发的软件组件和仪器设计，将在名为 OpenPolScope.org 的既定门户网站上向用户和开发人员提供。
