Abstract
We explore the possibility of extending the depth of focus of an imaging lens with anasymmetric quartic phase-mask, while keeping the aberration within a relatively low level. Thiscan be intended, for instance, for ophthalmic applications, where no further digital processingcan take place, relying instead on the patient’s neural adaptation to their own aberrations. Wepropose a computational optimization method to derive the design-strength factor of the asymmetricprofile. The numerical and experimental results are shown. The optical experiment was conductedby means of a modulo-2pphase-only spatial light modulator. The proposed combination of theasymmetric mask and the lens can be implemented in a single refractive element. An exemplarycase of an extended-depth-of focus intraocular lens based on the proposed element is described anddemonstrated with a numerical experiment.
