"The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) project: a versatile platform for high contrast imaging experiments (Joint AAO/Macquarie University Colloquium)"
Abstract. The Subaru Coronagraphic Extreme AO (SCExAO) instrument consists of a high performance Phase Induced Amplitude Apodization (PIAA) coronagraph combined with an extreme Adaptive Optics (AO) system operating in the near-infrared (H band). The extreme AO system driven by the 2000 element deformable mirror will allow for Strehl ratios>90% to be achieved in the H-band when it goes closed loop this year. This makes the SCExAO instrument a powerful platform for high contrast imaging down to angular separations of the order of 1 lambda/D.
I will discuss the development and latest performance of the instrument. In addition I will outline several exciting guest instruments which will expand the capabilities of SCExAO over the next few years; namely CHARIS which is an integral field spectrograph, VAMPIRES, a visible aperture masking experiment based on polarimetric analysis of circumstellar disks, FIRST and DRAGONFLY, photonic based aperture masking interferometers and PANDORA, an extreme AO fed diffraction limited spectrograph capable of 1 m/s RV precision on nearby M-dwarfs.
I will conclude the talk outlining the PANOTES project, our new and exciting project at the cross roads of scientific research and public outreach aimed at detecting transiting exoplanets with off the shelf DSLR cameras.
