To improve ophthalmic adaptive optics speed and compensate for ocular wavefront aberration of high temporal frequency, the adaptive optics wavefront correction has been implemented with a control scheme including 2 parallel threads; one is dedicated to wavefront detection and the other conducts wavefront reconstruction and compensation. With a custom Shack-Hartmann wavefront sensor that measure...

State University of New York at Stony Brook 2A two-level factorial design can be uniquely represented by a polynomial indicator function. Therefore, properties of factorial designs can be studied through their indicator functions. This paper shows that indicator function is an effective tool in studying two-level factorial designs. Indicator function is used to generalize aberration criterion o...

This paper provides a mathematical approach to the study of chromatic aberration in metalenses. It is shown that radiation given wavelength refracted according generalized Snell's law, which together with notion envelope, yields existence phase discontinuities. then used establish quantitative measure dispersion metalenses, concluding visible spectrum it has same order magnitude as for standard...
