High Contrast Imaging and Wavefront Control with a PIAA Coronagraph: Laboratory System Validation
Olivier Guyon, Eugene Pluzhnik, Frantz Martinache +5
The Phase-Induced Amplitude Apodization (PIAA) coronagraph is a high performance coronagraph concept able to work at small angular separation with little loss in throughput. We pre…

Coronagraphic Low Order Wavefront Sensor: Principle and Application to a Phase-Induced Amplitude Coronagraph
Olivier Guyon, Taro Matsuo, Roger Angel
High contrast coronagraphic imaging of the immediate surrounding of stars requires exquisite control of low-order wavefront aberrations, such as tip-tilt (pointing) and focus. We p…
