Overview of focal plane wavefront sensors to correct for the Low Wind Effect on SUBARU/SCExAO
Sebastien Vievard, Steven Bos, Frederic Cassaing +15
The Low Wind Effect (LWE) refers to a phenomenon that occurs when the wind speed inside a telescope dome drops below m/s creating a temperature gradient near the telescope spide…
The polarimetric imaging mode of VLT/SPHERE/IRDIS II: Characterization and correction of instrumental polarization effects
R. G. van Holstein, J. H. Girard, J. de Boer +31
Context. Circumstellar disks and self-luminous giant exoplanets or companion brown dwarfs can be characterized through direct-imaging polarimetry at near-infrared wavelengths. SPHE…
The polarimetric imaging mode of VLT/SPHERE/IRDIS I: Description, data reduction and observing strategy
J. de Boer, M. Langlois, R. G. van Holstein +31
Context. Polarimetric imaging is one of the most effective techniques for high-contrast imaging and characterization of protoplanetary disks, and has the potential to be instrument…
Focal-plane wavefront sensing with the vector Apodizing Phase Plate
Steven P. Bos, David S. Doelman, Julien Lozi +6
In this article we show that the vector-Apodizing Phase Plate (vAPP) coronagraph can be designed such that the coronagraphic point spread functions (PSFs) can act as a wavefront se…
A snapshot full-Stokes spectropolarimeter for detecting life on Earth
Frans Snik, Christoph U. Keller, David S. Doelman +8
We present the design of a point-and-shoot non-imaging full-Stokes spectropolarimeter dedicated to detecting life on Earth from an orbiting platform like the ISS. We specifically a…
