"while taking fewer measurements... eliminates algorithm iterations... solves linear equation yielding details of aberrations introduced by microscope's optics, and corrects them... measures light intensity, phase... faster, more accurate... large field of view without repeat microscope refocusing... biomedical (digital pathology) with or without AI interpretation"
