Exceptional wavefront correction is required for coronagraphs on future space observatories
to reach 10-10 contrasts for direct imaging of rocky exoplanets around Sun-like stars. This …

Assessing and optimizing polarization performance in the context of ray-based optical
design can be challenging. We describe an approach to this problem that decouples …

Dichroic filters are used by instrument designers to split a field of view into different optical
paths for simultaneous measurement of different spectral bands. Quantifying the polarization …

The Giant Magellan Telescope (GMT) design consists of seven circular 8.4-m diameter
mirror segments that are separated by large> 30 cm gaps, creating the possibility of …

The presence of optical rotation due to the Berry phase and coating-induced linear
polarizations across a set of rays deteriorate the form of a point spread function. In this …

Our galaxy hosts∼ 300 billion stars. Ever since the first exoplanet was discovered in 1992,
over 5,000 more exoplanet discoveries have been confirmed, and the number is still …

Characterizing the atmospheres of Earth-sized planets necessitates of the advancement in
broadband wavefront control for coronagraph systems in large segmented telescopes. At the …

A new generation of telescopes with mirror diameters of 20 m or more, called extremely
large telescopes (ELTs), has the potential to provide unprecedented imaging and …

We present the design and fabrication of metasurface-type patterned wave plates for VIS
applications. The metasurface consists of a grating structure with periods much smaller than …

摘要 Polarization aberration will affect the accuracy of polarization measurement and the
polarization imaging effect of an off-axis optical imaging system, and thus it is necessary to …
