Woofer-tweeter adaptive optical system for atmospheric turbulence mitigation

A woofer-tweeter approach is presented for compensation of the atmospheric turbulence negative effects. As a wavefront corrector for mitigation of the low-order aberrations with large amplitude the 23 -channel bimorph deformable mirror was used. To compensate for high-order aberrations with small amplitude the stacked-actuator deformable mirror with 55 control elements was exploited.
