摘要

We describe in this paper the plans for a high contrast imaging system to be deployed on Subaru Telescope. This system makes efficient use of both the new curvature AO systems at Subaru which recently had first light, and the HiCIAO camera, which will be completed in 2007. The proposed system will use "focal plane wavefront sensing" (FPWFS), a scheme where focal plane images are used to measure the wavefront. It will also use the highly efficient PIAA coronagraph. We show that these choices will result in a highly efficient high-contrast imaging instrument. Key techniques for this projects are being demonstrated in our high contrast testbed at Subaru Telescope.
