Outline of Final Research Achievements

For directly detecting extrasolar planets (planets orbiting around stars other than the Sun), we developed a high-contrast astronomical instrument to strongly reject bright starlight which is obstacle to detection of faint planetary light. We proposed new high-contrast techniques (a pupil-remapping optical system for focal-plane phase-mask coronagraphs, a polarimetric technique based on speckle decorrelation method, and so on), and carried out computer simulation and laboratory demonstration to evaluate the performance of the proposed techniques. Results of the computer simulation and the laboratory demonstration suggest that the proposed techniques can strongly reject bright starlight even when using a telescope which is not optimized for observations of extrasolar planets.
