Development of Scientific CMOS Imagers for Astronomy

这个项目的目标是开发用于天文学和其他科学学科的科学级CMOS成像探测器。这些新的探测器可以补充现有的CCD技术，如引导相机、波前传感器和高速成像仪。然而，随着技术的成熟，CMOS成像仪可能会取代ccd，因为它们成本低，而且易于在最先进的大面积硅片上制造。研究分为三个阶段。首先，开发CMOS成像仪的测试设备，以便与当今科学的CCD探测器进行直接、定量的比较。其次，评估现有CMOS器件，以获得其真实的性能特征。第三，开发用于天文用途的优化CMOS成像仪，包括设计和制造变更、正面涂层、定制封装、混合传感器和背照处理。在电子成像“科学工具包”将开发作为一个原型的教育工具，为高中学生使用CMOS成像仪和教室个人电脑。

AST-9876630Lesser, MichaelThe goal of this project is to develop scientific grade CMOS imaging detectors for use in astronomy and other scientific disciplines. These new detectors can complement existing CCD technology for such applications as guide cameras, wavefront sensors, and high-speed imagers. As the technology matures, however, CMOS imagers may replace CCDs because of their low cost and ease of manufacture on state-of-the-art, large area silicon wafers.The research is focussed into three phases. First, developing a test facility for CMOS imagers, which allows direct, quantitative comparison with today's scientific CCD detectors. Second, evaluating existing CMOS devices to obtain their real performance characteristics. And third, developing optimized CMOS imagers for astronomical use, including design and fabrication changes, frontside coatings, custom packaging, hybridized sensors, and back illuminated processing. In electronic imaging "science kit" will be developed as a prototype educational tool for high school students using CMOS imagers and classroom personal computers.
