Abstract

The calibration wavefront system for GPI will measure the complex wavefront at the apodized pupil and provide slow phase corrections to the AO system to mitigate against errors that would cause a loss in contrast. This talk describes both the low-order and high-order sensors in the calibration wavefront sensor and how the information is combined to form the wavefront estimate before the coronagraph. Expected performance for this wavefront sensor will also be described for typical observing scenarios. Finally, we will show labratory results from our calibration testbed that demonstrate the instrument performance at levels commensurate with those required on the GPI instrument.
