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…
Japan's Possible Contributions for Coronagraph of the Habitable Worlds Observatory (HWO)
Keigo Enya, Kenta Yoneta, Naoshi Murakami +20
In this paper, we describe Japan's possible contributions for coronagraph of the Habitable Worlds Observatory (HWO) based on our independent study. We are considering to contribute…
Experimental Validation for Serial Conjunction of Diffraction-limited Coronagraph and Fiber Nuller
Satoshi Itoh, Taro Matsuo, Reiki Kojima +2
We report the experimental results of a serially conjoined nuller system, which combines a type of Lyot coronagraph with a fiber nuller. The utilized one-dimensional diffraction-li…
A Coronagraph with a Sub- IWA and a Moderate Spectral Bandwidth
Satoshi Itoh, Taro Matsuo
Future high-contrast imaging spectroscopy with a large segmented telescope will be able to detect atmospheric molecules of Earth-like planets around G- or K-type main-sequence star…
Point Spread Function of Hexagonally Segmented Telescopes by New Symmetrical Formulation
Satoshi Itoh, Taro Matsuo, Shibai Hiroshi +1
A point spread function of hexagonally segmented telescopes is derived by a new symmetrical formulation. By introducing three variables on a pupil plane, the Fourier transform of p…
