Schematic of optical setup used to acquire wavefront data. Red laser light is collimated and passed through linear polarizers (LP), a polarizing beam-splitter (PBS), a 5x beam expander, a quarter-wave plate, a deformable mirror (DM), and a relay telescope before being measured by a Shack-Hartmann wavefront sensor (SHWFS). The symbols represent the polarization of the light while traveling from left to right in the system.
