The broader impact/commercial potential of this Small Business Technology Transfer Research (STTR) Phase I project is that smaller and less expensive medical endoscopes will be made possible, which will allow physicians to see better inside the human body. These devices will shorten recovery times, improve diagnosis and treatment, move procedures from operating rooms to exam rooms, and lower health care costs. In addition, physicians will be able to visualize in parts of the body that were previously inaccessible. Health care will be improved throughout the world, particularly in developing countries. This project advances the state of the art in the design of micro-optics as well as their manufacture. Large arrays of tiny but precise lens components will be assembled in one operation, drastically reducing costs. The micro-optics and advanced manufacturing techniques developed in this project will also be applicable to other imaging systems.This project will develop new designs for micro-optics with a particular emphasis on medical endoscopes and new manufacturing techniques. High performance free-form optics that use multiple fields will be designed to produce images within acceptable limits for biomedical optics and be manufacturable. A high volume, precision manufacturing process will be developed for these optics. Wafer level assembly technology will be used to combine multiple arrays of micro-optic elements. Lens systems thus produced will be tested to determine whether they are within the design specification for mechanical and optical performance. Optical camera calibration and an image processing pipeline will be developed to combine the multiple fields and correct aberrations and produce accurate image reconstruction.

这个小企业技术转让研究（STTR）第一阶段项目更广泛的影响/商业潜力是，将使更小、更便宜的医用内窥镜成为可能，这将使医生能够更好地观察人体内部。这些设备将缩短恢复时间，改善诊断和治疗，将程序从手术室转移到检查室，并降低医疗保健成本。此外，医生将能够可视化以前无法访问的身体部位。 全世界，特别是发展中国家的卫生保健将得到改善。该项目推进了微光学设计及其制造的最新技术水平。 微小但精确的透镜组件的大阵列将在一次操作中组装，大大降低了成本。本项目开发的微光学和先进制造技术也将适用于其他成像系统。本项目将开发新的微光学设计，特别是医疗内窥镜和新的制造技术。 使用多个场的高性能自由形式光学器件将被设计为在生物医学光学器件的可接受限度内产生图像，并且是可制造的。将为这些光学器件开发高容量、高精度的制造工艺。 晶圆级组装技术将用于联合收割机组合多个微光学元件阵列。将对由此生产的透镜系统进行测试，以确定其是否符合机械和光学性能的设计规范。 将开发光学摄像机校准和图像处理流水线，以联合收割机组合多个场并校正像差并产生准确的图像重建。
