The~ 39-m European Extremely Large Telescope (E-ELT) will be the largest telescope ever
built. This makes it particularly suitable for sensitive polarimetric observations, as polarimetry …

Experience with the Hubble Space Telescope has shown that accurate models of optical
performance are extremely desirable to astronomers, both for assessing feasibility and …

We derive formulae for all parameters defining the field astigmatism of misaligned two mirror
telescopes with arbitrary geometries and with stop positions anywhere on the line …

We introduce and compare schemes to form wide-field polarimetric images from radio-
interferometric mosaic and single-dish observations. We concentrate on two schemes based …

Pupil mapping is a promising and unconventional new method for high-contrast imaging
being considered for terrestrial exoplanet searches. It employs two (or more) specially …

We present the effects of misalignments on the field dependence of the third-order
aberration fields of traditional, two-mirror astronomical telescopes in the context of nodal …

The 13.7-m Czerny-Turner spectrograph at the McMath solar telescope is evaluated with
regard to polarization properties. Let I_‖= the transmissivity of the spectrograph for incident …

Direct imaging of potentially habitable planets is challenging because of the relative
proximity of the planet to the star and the low flux ratio (typically well under 1e-9 in the …

This paper presents a systematic and in-depth discussion for the aberration fields of off-axis
two-mirror astronomical telescopes with an offset pupil that is induced by lateral …

Written by an experienced teacher and author, this must-have source for work with
polarimetric equipment and polarimetry in astronomy conveys the knowledge of the …
