Development of Scientific CMOS Imagers for Astronomy

AST-9876630 Lesser，Michael该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，用于引导相机、波前传感器和高速成像仪等应用。然而，随着技术的成熟，由于其低成本和易于在最先进的大面积硅片上制造而有可能取代ccd。首先，开发一种用于cmos成像器的测试设备，它可以与当今的科学ccd探测器进行直接、定量的比较。其次，对现有的CMOS器件进行评估，以获得其真实的性能特性。第三，开发用于天文用途的优化的CMOS成像器，包括设计和制造变化、正面涂层、定制封装、混合传感器和背光处理。在电子成像方面，“科学工具包”将被开发为高中生使用cmos成像器和教室个人电脑的原型教育工具。

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.
