Abstract

The Laser guide Star Sensor Integrated Extreme adaptive optics (LASSIE) project seeks to improve extreme adaptive optics (ExAO) performance for dim objects using a laser guide star (LGS) AO system to correct for higher spatial frequency phase aberrations minimizing the flux required for the NGS wavefront measurement. As part of that effort, the LASSIE program is exploring avenues for improving LGS AO performance through pre-compensation of the uplink beam and improved wavefront sensor design. Various systems designs are explored to estimate performance improvement that may be obtained with a pre-compensated LGS AO system and an optimized wavefront sensor design relative to a standard ExAO system.
