Wavefront stabilization is a fundamental challenge to high contrast imaging of exoplanets.
For both space and ground observations, wavefront control performance is ultimately limited …

Polarization aberrations are found in most optical components due to a materials-differing
response to s-and p-polarizations. This differing response can manifest either as …

The Thirty Meter Telescope (TMT) is a future generation telescope proposed to be located in
Mauna Kea, Hawaii or in La Palma in the Canary Islands. The telescope will have a …

Polarization imaging technology expands the dimensions of the object and enriches its
basic information compared to traditional imaging methods. During the imaging process, the …

In this paper we examine several contrast-degrading static signature sources present in
current terrestrial exoplanet Lyot Coronagraph/Telescope optical systems. These are …

Multilayer coatings induce a significant polarization aberration in optical systems with high
numerical aperture (NA) and wide field of view, which will cause wavefront distortion and …

An optical design program, Polaris-M, developed at the University of Arizona incorporates
many advanced polarization analysis features. At the core of the program is a three …

In 2014 we presented a concept for an Evolvable Space Telescope (EST) that was
assembled on orbit in 3 stages, growing from a 4x12 meter telescope in Stage 1, to a 12 …

Low polarization systems have important advantages in many applications. Thanks to be
with seven free design parameters, three-mirror reflective systems have good potential to …

Over the past few years, we have developed a concept for an evolvable space telescope
(EST) that is assembled on orbit in three stages, growing from a 4× 12-m telescope in Stage …
