英文摘要 |
Using an optical vortex coronagraph (OVC) is one of the most promising techniques for directly
imaging exoplanets because of its small inner working angle and high throughput。This paper
presents the design and laboratory demonstration performance of an OVC based on liquid crystal polymers (LCPs) at 633 nm and 1520 nm。The OVC can deliver good performance in laboratory tests and achieve a contrast of 10-6 at an angular distance of 3 λ/D, which can be implemented for imaging young giant exoplanets in combination with extreme adaptive optics。 |
