Measurement range of phase retrieval in optical surface and wavefront metrology.

Phase retrieval employs very simple data collection hardware and iterative algorithms to determine the phase of an optical field. We have derived limitations on phase retrieval, as applied to optical surface and wavefront metrology, in terms of the speed of beam (i.e., f-number or numerical aperture) and amount of aberration using arguments based on sampling theory and geometrical optics. These...

Wavefront spacing and Gouy phase in presence of primary spherical aberration.

We study the Gouy phase of a scalar wavefield that is focused by a lens suffering from primary spherical aberration. It is found that the Gouy phase has different behaviors at the two sides of the intensity maximum. This results in a systematic increase of the successive wavefront spacings around the diffraction focus. Since all lenses have some amount of spherical aberration, this observation ...

Complete Modal Representation with Discrete Zernike Polynomials - Critical Sampling in Non Redundant Grids

Zernike polynomials (ZPs) form a complete orthogonal basis on a circle of unit radius. This is useful in optics, since a great majority of lenses and optical instruments have circular shape and/or circular pupil. The ZP expansion is typically used to describe either optical surfaces or distances between surfaces, such as optical path differences (OPD), wavefront phase or wave aberration. Theref...

Wave aberration of human eyes and new descriptors of image optical quality and visual performance.

The expansion of wavefront-sensing techniques redefined the meaning of refractive error in clinical ophthalmology. Clinical aberrometers provide detailed measurements of the eye's wavefront aberration. The distribution and contribution of each higher-order aberration to the overall wavefront aberration in the individual eye can now be accurately determined and predicted. Using corneal or ocular...

Third-order aberration analysis of tilted-pupil optical systems∗

The aberration field of an optical system with a tilted pupil is explored through expanding the vector expressions of the third-order wavefront aberrations. First, the vector forms of the wavefront aberrations are modified to obtain the aberration expressions with the pupil tilted; full field displays of coma and astigmatism in this situation are given. Then, the third-order aberration formulas...
