Combining a Diffraction-Limited Coronagraph with Fiber Nulling: A Demonstration of Serially Coupling Different Nullers

Satoshi Itoh, Taro Matsuo, Reiki Kojima +3

We present experimental results of an efficient small-IWA ($\sim$1 $\hat{I}»/D$) high contrast imaging approach realized by co-optimizing a coronagraph front-end with a fiber nulling 2nd…
