This award is for a project to build an ultra-stable frequency calibrator for high resolution optical spectrography using a comb laser. The purpose of developing such a system is to be able to extend the indirect detection of extra-solar planets to lower mass objects, i.e. those comparable to the Solar System's terrestrial planets rather than the gas-giants. The indirect spectroscopic techniques have proven to be successful at finding extra-solar planets and the technology to be developed in this award will permit the spectral line positional changes of the parent star, which infer the existence and mass of a planetary companion, to be measured to significantly higher accuracy than before, thereby extending the technique to lower mass planets. The award will demonstrate that comb lasers can be used for this application and the technology and techniques will be distributed to the general community. In addition, undergraduate and graduate students will undergo training in instrumentation. This is a very topical field and the existence of extra-solar planets, especially those resembling the Earth, will capture the public imagination.

该奖项是为一个使用梳状激光器的高分辨率光谱仪建立超稳定频率校准器的项目。开发这样一个系统的目的是能够将太阳系外行星的间接探测扩展到质量较低的物体，即那些与太阳系的类地行星相当的物体，而不是气体巨星。间接光谱技术已被证明在寻找太阳系外行星方面是成功的，本奖项将开发的技术将允许测量母星星的光谱线位置变化，从而推断行星伴星的存在和质量，其精度比以前高得多，从而将该技术扩展到较低质量的行星。该奖项将证明梳状激光器可用于此应用，并将技术和技术分发给广大社区。 此外，本科生和研究生将接受仪器仪表培训。 这是一个非常热门的领域，太阳系外行星的存在，特别是那些类似地球的行星，将吸引公众的想象力。
