Abstract
A novel wavefront sensor (Z-ViewTM) using a two dimensional diffractive grating has been developed at Ophthonix, Inc. Based on the Talbot self-imaging theory, a CMOS camera is placed behind the grating to capture the first Talbot image of the aberrated wavefront. This captured Talbot image is analyzed to recover the wavefront aberration. The diffractive grating wavefront sensor has been used in Ophthonix's Z-View Aberrometer, an objective refractive vision assessment system which is now commercially used in optometrist's offices/clinics across the United States of America. Coupled with a deformable mirror and other auxiliary optics systems, Z-View wavefront sensor forms the A-View adaptive optic vision correction system at Ophthonix. This A-View system is used to study the effect of complete wavefront correction in human vision, and has potential application in prescribing Ophthonix's wavefront-guided iZonTM lenses. In this paper, the wavefront sensing principle of this novel diffractive wavefront sensor and its applications will be discussed.
