GREGOR ‐ optical design considerations

open access: yesAstronomische Nachrichten, 2003
AbstractAfter many years of successful work the Gregory Coudé Telescope (GCT) is going to be replaced by GREGOR. This new 1.5 m telescope is the result of design considerations which to a wide extent are based on new technologies. Special aspects of the design are presented, including measures to compensate for optical aberrations caused by ...

Transformation-designed optical elements

open access: yesOptics Express, 2007
We describe transformation design of optical elements which, in addition to image transfer, perform useful operations. For one class of operations, including translation, rotation, mirroring and inversion, an image can be generated that is ideal in the sense of the perfect lens (combining both near- and far-field components in a flat, unit transfer ...

Optical and mechanical design of the extreme AO coronagraphic instrument MagAO-X

open access: yes, 2018
Here we review the current optical mechanical design of MagAO-X. The project is post-PDR and has finished the design phase. The design presented here is the baseline to which all the optics and mechanics have been fabricated.

A Novel Focal Length Measurement Method for Center-Obstructed Omni-Directional Reflective Optical Systems

open access: yesApplied Sciences, 2019
An omni-directional optical system can be used as a surveillance camera owing to its wide field angle. In cases in which a system is designed with a central screen obscuring structure to increase the resolution of the off-axis field, however, the ...
