Sentence examples for pupil phase from inspiring English sources

The design of pupil phase filters that super-resolve the axial intensity distribution with controlled side-lobe peak intensity under high numerical aperture conditions can be accomplished by incorporating the theory of electromagnetic diffraction in the method of generalized projections (MGP).

An analytical method for a total control of the light-intensity distribution at the focus of an optical system by simple pupil-plane phase mask is presented.

The original works done by Dowski and Cathey introduce the use of a cubic phase pupil mask to extend the depth of field.

By properly designing a phase pupil mask to modulate or encode the optical images and then digitally restoring them, one can greatly extend the depth of field and improve image quality.
