| Research Abstract |
For an important challenge of direct observation of exoplanets using a coronagraph applicable to an infrared space telescope, we developed a low temperature vacuum chamber and an experimental system inside the chamber. Furthermore, we developed new designed pupil masks for practical use and carried out the coronagraph experiments using the masks at visible wavelength. As the result, we achieved a necessary contrast for the direct observation of exoplanets at infrared wavelength. Additionally, we simulated the wavefront error, which is great enemy of a coronagraph, and the detection capability of habitable zone object.
