Super Resolved Imaging with Adaptive Optics
Robin Swanson, Esther Y. H. Lin, Masen Lamb +2
Astronomical telescopes suffer from a tradeoff between field of view (FoV) and image resolution: increasing the FoV leads to an optical field that is under-sampled by the science c…
Tuning the MAPS Adaptive Secondary Mirror: Actuator Control, PID Tuning, Power Spectra and Failure Diagnosis
Jess A. Johnson, Amali Vaz, Manny Montoya +17
The MMT Adaptive optics exoPlanet characterization System (MAPS) is currently in its engineering phase, operating on-sky at the MMT Telescope on Mt. Hopkins in southern Arizona. Th…
Performance estimation of photonic integrated wavefront corrector for single-mode fiber coupling
Dhwanil Patel, Momen Diab, Ross Cheriton +3
Many modern astronomical instruments rely on the optimal coupling of starlight into single-mode fibers (SMFs). For ground-based telescopes, this coupling is limited by atmospheric…
Experimental demonstration of photonic phase correctors based on grating coupler arrays and thermo-optic shifters
Momen Diab, Ross Cheriton, Jacob Taylor +9
In ground-based astronomy, the ability to couple light into single-mode fibers (SMFs) is limited by atmospheric turbulence, which prohibits the use of many astrophotonic instrument…
