InnoPOL: an EMCCD imaging polarimeter and 85-element curvature AO system on the 3.6-m AEOS telescope for cost effective polarimetric speckle suppression
David Harrington, Svetlana Berdyugina, Mark Chun +3
The Hokupa'a-85 curvature adaptive optics system components have been adapted to create a new AO-corrected coudé instrument at the 3.67m Advanced Electro-Optical System (AEOS) tele…
Astrometric Calibration of the Gemini NICI Planet-Finding Campaign
Thomas L. Hayward, Beth A. Biller, Michael C. Liu +6
We describe the astrometric calibration of the Gemini NICI Planet-Finding Campaign. The Campaign requires a relative astrometric accuracy of 20 mas across multi-year time…
The Gemini NICI Planet-Finding Campaign: The Companion Detection Pipeline
Zahed Wahhaj, Michael C. Liu, Beth A. Biller +7
We present the high-contrast image processing techniques used by the Gemini NICI Planet-Finding Campaign to detect faint companions to bright stars. NICI (Near Infrared Coronagraph…
Automatic sensitivity-adjustment for a curvature sensor
Aglae Kellerer, Mark Chun, Christ Ftaclas
There are different techniques to sense the wavefront phase-distortions due to atmospheric turbulence. Curvature sensors are practical in their sensitivity being adjustable to the…
