چکیده
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 exquisite levels of performance.

W. M. Keck Observatory Next-Generation Adaptive Optics Facility: Science Operations
The W. M. Keck Observatory is currently engaged in the conceptual design of a powerful new adaptive optics (AO) science capability providing precision AO correction in the near infrared (NIR) and visible and faint object multiplexed integral field spectroscopy. In this poster, we present the conceptual design of the Science Operations for this Next Generation Adaptive Optics (NGAO) facility. We...
متن کاملModeling low order aberrations in laser guide star adaptive optics systems.
When using a laser guide star (LGS) adaptive optics (AO) system, quasi-static aberrations are observed between the measured wavefronts from the LGS wavefront sensor (WFS) and the natural guide star (NGS) WFS. These LGS aberrations, which can be as much as 1200 nm RMS on the Keck II LGS AO system, arise due to the finite height and structure of the sodium layer. The LGS aberrations vary signific...
متن کاملQuasi-static aberrations induced by laser guide stars in adaptive optics.
Laser Guide Star Adaptive Optics (LGS AO) systems use the return from an artificial guide star to measure the wavefront aberrations in the direction of the science object. We observe quasi-static differences between the measured wavefront and the wavefront aberration of the science object. This paper quantifies and explains the source of the difference between the wavefronts measured using an L...
متن کاملAstronomical Science with Adaptive Optics at the W. M. Keck Observatory
The first refereed science papers based on data with the Keck II natural guide star (NGS) and laser guide star (LGS) adaptive optics (AO) system were published in 2000 January and 2005 May, respectively. As of the end of 2012 a total of 260 refereed science papers have been published based on Keck NGS AO data and 152 with the Keck LGS AO system. This paper provides an overview of the first doze...
متن کاملFocus and pointing adjustments necessary for laser guide star adaptive optics at the W. M. Keck Observatory
The W. M. Keck Observatory Adaptive Optics (AO) team recently celebrated a milestone first AO-corrected image with the new Laser Guide Star (LGS) system. This paper details focus and pointing changes implemented for the LGS AO system. The combination of variable sodium altitude, elevation-dependent distance to the LGS, off-axis projection, and equipment flexure require both focus and pointing a...
