Resolving the Young 2 Cygni Run-away Star into a Binary using iLocater

Justin R. Crepp, Jonathan Crass, Andrew J. Bechter +30

Precision radial velocity (RV) spectrographs that use adaptive optics (AO) show promise to advance telescope observing capabilities beyond those of seeing-limited designs. We are b…

Centroiding and Extraction of Tip/Tilt Information from Nonlinear Curvature Wavefront Sensor Measurements

Caleb A. Abbott, Justin R. Crepp, Stanimir O. Letchev +1

The nonlinear curvature wavefront sensor (nlCWFS) uses multiple (typically four) out-of-focus images to reconstruct the phase and amplitude of a propagating light beam. Because the…

Performance of the Nonlinear Curvature Wavefront Sensor as a Function of Scintillation Strength

Stanimir Letchev, Justin R. Crepp, Caleb G. Abbott +3

Local amplitude aberrations caused by scintillation can impact the reconstruction process of a wavefront sensor (WFS) by inducing a spatially non-uniform intensity at the pupil pla…
