| Outline of Annual Research Achievements |
The purpose of the research is to develop on the Subaru Telescope a high contrast imaging system capable of taking images of Jupiter-like planets in reflected light.
A key part of the activity is to develop and install on the Subaru Extreme Adaptive Optics (SCExAO) system a new high-performance camera that can detect individual photons and measure their wavelength. The camera uses the Micro-Kinetic Inductance Detectors (MKIDs) technology at near-infrared wavelength, and will measure residual errors in the optical system at least 1000 times per second, so that they can be corrected.
A second goal is to plan the SCExAO system to evolve toward an instrument capable of imaging and characterizing habitable exoplanets on the Thirty Meter Telescope (TMT). Adaptive optics (correction of optical aberration introduced by the atmosphere) and coronagraphy (optics to mask starlight and preserve planet light) technologies are developed as part of our effort to enable high contrast imaging.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We have not encountered any major problem in the development of the new camera or the development of new high contrast imaging techniques. Our initial plan included the delivery of the camera in this fiscal year. We have delayed the camera delivery by a few month, to summer 2017 to allow for more testing, and to concentrate our efforts at Subaru Telescope for the on-sky operation. In other areas of the project (development of techniques for exoplanet imaging, concepts for TMT instrument), we have made very significant progress and completed more work than originally planed:(1) We will use the IRD spectrograph, for high resolution spectroscopy of exoplanets,(2) The coronagraph design has advanced and we have solved the chromaticity limitation, (3) We have developed an algorithm to predict atmospheric turbulence in real-time.

| Strategy for Future Research Activity |
To achieve our research goals, we need to control and correct aberrations introduced by the atmosphere. To do so, a high speed high sensitivity camera will be installed on the Subaru Telescope to measure aberrations faster than 1 kHz. The new camera (MKIDs) will be completed in FY2017, and will be tested and delivered in summer 2017. It will then be combined with the existing SCExAO instrument on the Subaru Telescope. This should proceed quickly, as we have already completed the re-build of SCExAO to be compatible with the MKIDs camera. Our team will then perform system testing with the SCExAO artificial source to validate system functions. On-sky observations with the MKIDs camera will start in fall 2017.
We will continue development of advanced coronagraph and wavefront control techniques. The MKIDs camera will become a key element of the SCExAO instrument wavefront control architecture, and will deliver deeper contrast for exoplanet imaging. Science observations will start during FY2017.
During FY2017, our research team will also design the major features of the instrument for TMT, using experience learned from work on the Subaru Telescope.
