Shack-Hartmann sensor as an imaging system with a phase diversity
Oleg Soloviev, Hieu Thao Nguyen, Vitalii Bezzubik +3
Conventional methods of wavefront reconstruction from the raw data of the Shack-Hartmann sensor use the focal spot shifts and discard the high-frequency information about the wavef…
