The Zernike polynomials are a complete set of continuous functions orthogonal over a unit
circle. Since first developed by Zernike in 1934, they have been in widespread use in many …

Publisher Summary This chapter presents the computation of the point-spread function of
optical imaging systems and the characterization of these systems by means of the …

New Bessel-series representations for the calculation of the diffraction integral are
presented yielding the point-spread function of the optical system, as occurs in the Nijboer …

We show that, in order to attain complete polarization control across a beam, two spatially
resolved variable retardations need to be introduced to the light beam. The orientation of the …

We consider using phase retrieval (PR) to correct phase aberrations in an optical system.
Three measurements of the point-spread function (PSF) are collected to estimate an …

Taking the classical Ignatowsky/Richards and Wolf formulas as our starting point, we present
expressions for the electric field components in the focal region in the case of a high …

We present a comprehensive review and tutorial on emerging numerical electromagnetic
simulations of optical imaging systems based upon three-dimensional full-vector solutions of …

The high NA= 0.55 EUV scanner has an obscuration in the pupil. This has led to the choice
to expand the aberration wave-front not in Zernikes anymore, but in other, orthogonal, basis …

We give the proof of principle of a new experimental method to determine the aberrations of
an optical system in the field. The measurement is based on the observation of the intensity …

Purpose We propose the B essel C ircular F unctions as alternatives of the Z ernike C ircle P
olynomials to represent relevant circular ophthalmic surfaces. Methods We assess the fitting …
