Analyzing Variation in Phase Delays Across Phase Plates With a Quadrature Polarization Interferometer
Cesar Laguna
In order for telescopes to obtain good and precise images they need to see through atmospheric turbulence. To accomplish this and compensate for atmospheric turbulence we use Adapt…

Deformable mirror-based pupil chopping for exoplanet imaging and adaptive optics
Javier Perez Soto, Cesar Laguna, Benjamin L. Gerard +3
Due to turbulence in the atmosphere images taken from ground-based telescopes become distorted. With adaptive optics (AO) images can be given greater clarity allowing for better ob…
