A method of polarization ray tracing for calculating the instrumental polarization function of
an optical system using the Jones calculus is presented. Polarization ray tracing …

Abstract The well-known Fourier Transform relationship between the complex illumination
function and the diffraction pattern of an aperture has been applied to measurements of the …

An undersampled point‐spread function (PSF) may interact with the microstructure of a solid‐
state detector such that the total flux detected can depend sensitively on where the PSF …

We describe the influence of Fresnel propagation in apodized-pupil coronagraphs and
introduce a methodology to compensate for propagated wavefront aberrations. We start from …

Well over 700 exoplanets have been detected to date. Only a handful of these have been
observed directly. Direct observation is extremely challenging due to the small separation …

High-contrast coronagraphic imaging is challenging for telescopes with central obstructions
and thick spider vanes, such as the Subaru Telescope. We present in this article the first …

The first results of a new approach to ground-based stellar coronagraphy are reported. A
coronagraph has been equipped with an image-motion compensation system for the …

This paper examines the polarization aberrations in optical systems of isotropic radially
symmetric weak polarizers in the paraxial approximation. Optical systems which fit this …

High‐resolution spectropolarimetry sometimes suffers from a spectral modulation in
polarization and position angle. It is shown that this artifact can be attributed to multiple …

We investigate, via a Monte Carlo computer code, the effect of multiple Thomson scattering
on the continuum polarization arising from axisymmetric circumstellar envelopes such as …
