Keck Telescope Wavefront Errors: Implications for NGAO
نویسندگان
چکیده
This note details the effect of telescope static and dynamic wavefront errors on the performance of future AO systems at Keck observatory. Measurements at Keck are used to bound probable values of the input errors. Current understanding of all errors appears sufficient to design the NGAO system. A notable exception is the full aperture tip tilt vibrations at 29 Hz. These errors appear to have significant impact on sky coverage.

The Low Order Wavefront Sensor (LOWFS) assembly is located at the focus of the first relay and contains as a minimum 2 Tip/Tilt WFS, 1 TTFA WFS, 1 TWFS WFS and 1 PSF monitor. The NGAO LOWFS assembly is a critical part of the NGAO system as it initiates acquisition and all subsequent observation modes such as on and off-chip dithering, including sub-pixel dithering, and non-sidereal tracking at ...
متن کاملEffect of segmented telescope phasing errors on adaptive optics performance
The largest existing optical telescopes and the next generation of extremely large telescopes are all segmented telescopes. The primary mirror segments must be phased in order to attain the diffraction limit of the telescope. In this paper, we investigate the effect of phasing errors on image quality delivered by the adaptive optics systems at the W. M. Keck Observatory using both simulations a...
