The broader impact/commercial potential of this Partnerships for Innovation – Research Partnerships (PFI-RP) project will address the long-standing challenge of making cheaper infrared (IR) thermal imaging systems (i.e., “night vision”), long used for defense & military applications. The potential of IR thermal imaging and detection for applications in consumer electronics, transportation, medical imaging, robotic and aerospace has also been known for decades, but the high cost of IR cameras & detectors has impeded widespread use of these systems in consumer markets. The proposed technology consists of a new class of inexpensive materials for the creation and production of windows, lenses and other optical components of IR thermal imaging systems. The proposed novel class of synthetic polymers will be used for the first time in IR optical applications at the lower cost and easier processing of conventional materials. This advance would further enable the development of lower-cost IR imaging systems for mass deployment in consumer markets. The project will be focused on a new class of IR optical materials known as 'Chalcogenide Hybrid Inorganic/Organic Polymers' (CHIPs). These polymers have the highest refractive index of any synthetic polymer known to date and possess superior IR transparency, in comparison to classical synthetic polymers. CHIPs materials can be processed into optical elements, such as lenses or windows, for IR thermal imaging. In this project, the development of large-scale synthetic methods of CHIPs materials with desirable optical and thermomechanical properties will be conducted. New processing methods will be developed using classical melt processing techniques, such as molding/casting or hot pressing to prepare high quality windows and lenses. Additive manufacturing techniques, such as FFM-3D printing, will also be employed for the first time to rapidly prototype CHIPs lenses and windows. The proposed project will optimize design of optical components at the systems level.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该创新-研究伙伴关系（PFI-RP）项目的广泛影响/商业潜力将解决长期存在的挑战，即制造更便宜的红外（IR）热成像系统（即“夜视”），长期用于国防和军事应用。红外热成像和检测在消费类电子产品、交通运输、医疗成像、机器人和航空航天领域的应用潜力几十年来一直为人所知，但红外相机和探测器的高成本阻碍了这些系统在消费市场的广泛应用。提出的技术由一类新的廉价材料组成，用于制造和生产窗口、透镜和红外热成像系统的其他光学部件。这种新型合成聚合物将首次用于红外光学应用，其成本较低，而且比传统材料更容易加工。这一进展将进一步推动低成本红外成像系统的发展，以便在消费市场上大规模部署。该项目将专注于一种新型红外光学材料，称为“硫系杂化无机/有机聚合物”（CHIPs）。这些聚合物具有最高的折射率的任何合成聚合物已知的日期，并具有优越的红外透明度，与经典的合成聚合物相比。芯片材料可以加工成光学元件，如透镜或窗口，用于红外热成像。在本项目中，将进行具有理想光学和热机械性能的芯片材料的大规模合成方法的开发。新的加工方法将使用经典的熔体加工技术，如成型/铸造或热压来制备高质量的窗户和镜片。增材制造技术，如FFM-3D打印，也将首次用于快速原型芯片镜头和窗户。该计划将在系统层面优化光学元件的设计。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
