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 (1 ) high contrast imaging approach realized by co-optimizing a coronagraph front-end with a fiber nulling 2nd…

Integrated coronagraphy and wavefront sensing with the PIAACMC
Sebastiaan Y. Haffert, Jared R. Males, Olivier Guyon
Uncorrected wavefront errors create speckle noise in high-contrast observations at small inner-working angles. These speckles can be sensed and controlled by using coronagraph inte…
