Integrated astrophotonic phase control for high resolution optical interferometry
Ross Cheriton, Siegfried Janz, Glen Herriot +2
Long baseline optical interferometry and aperture synthesis using ground-based telescopes can enable unprecedented angular resolution astronomy in the optical domain. However, atmo…
Fast modulation and dithering for the NFIRAOS Pyramid Wavefront Sensor
Edward L. Chapin, David Andersen, Owen Brown +8
The Narrow Field InfraRed Adaptive Optics System (NFIRAOS) for the Thirty Meter Telescope (TMT) will use a natural guide star (NGS) Pyramid Wavefront Sensor (PWFS). A 32-mm diamete…
The Infrared Imaging Spectrograph (IRIS) for TMT: final software design update
Edward L. Chapin, Jennifer Dunn, Takashi Nakamoto +13
The InfraRed Imaging Spectrograph (IRIS) is the first-light client instrument for the Narrow Field Infrared Adaptive Optics System (NFIRAOS) on the Thirty Meter Telescope (TMT). No…
Geometric Distortion Calibration with Photo-lithographic Pinhole Masks for High-Precision Astrometry
Maxwell Service, Jessica R. Lu, Mark Chun +5
Adaptive optics (AO) systems deliver high-resolution images that may be ideal for precisely measuring positions of stars (i.e. astrometry) if the system has stable and well-calibra…
Multi-Conjugate Adaptive Optics Simulator for the Thirty Meter Telescope: Design, Implementation, and Results
Etsuko Mieda, Jean-Pierre Veran, Matthias Rosensteiner +5
We present a multi-conjugate adaptive optics (MCAO) system simulator bench, HeNOS (Herzberg NFIRAOS Optical Simulator). HeNOS is developed to validate the performance of the MCAO s…
The Infrared Imaging Spectrograph (IRIS) for TMT: closed-loop adaptive optics while dithering
Edward L. Chapin, Jennifer Dunn, David Andersen +17
The InfraRed Imaging Spectrograph (IRIS) is the first-light client instrument for the Narrow Field Infrared Adaptive Optics System (NFIRAOS) on the Thirty Meter Telescope (TMT). IR…
