A sensitive tip-tilt wave-front sensor for the multi-conjugate adaptive-optics system on the Gemini south telescope

用于双子座南望远镜多共轭自适应光学系统的灵敏倾斜波前传感器：该项目将为智利双子座南望远镜上的多共轭自适应光学系统GEMS建造一个灵敏的倾斜波前传感器。GEMS是一种独特的、革命性的新系统，它以与哈勃太空望远镜相似的分辨率在大范围内提供光学波长的近红外图像。有了这项技术的改进，就有可能对比目前使用这种新的波前传感器更微弱的物体进行这一检测。这将使GEMS能够以高角度分辨率例行研究外部星系的形态--极大地扩展了它的科学范围。还将获得当前可访问的所有对象的更清晰的图像，从而获得更高质量的科学数据。

A sensitive tip-tilt wavefront sensor for the multi-conjugate adaptive-optics system on the Gemini South telescope: This project will construct a sensitive tip-tilt wavefront sensor for GeMS, the multi-conjugate adaptive-optics system on the Gemini South telescope in Chile. GeMS is a unique and revolutionary new system that delivers near-infrared images at similar resolution to the Hubble Space Telescope at optical wavelengths over wide fields. With this improvement in technology it will be possible to do this on much fainter objects than is currently possible using this new wave-front sensor. This will allow GeMS to routinely study the morphologies of external galaxies at high angular resolution - greatly extending its science scope. Sharper images will also be obtained for all objects that are currently accessible, leading to higher quality science data.
