Quasi-static aberrations induced by laser guide stars in adaptive optics.

چکیده
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 LGS and a natural guide star at the W. M. Keck Observatory, which can be as high as 1000 nm RMS.

Modeling Laser Guide Star Aberrations
When using a laser guide star (LGS) adaptive optics system, quasi-static aberrations are observed between the measured wavefronts from the LGS wavefront sensor (WFS) and the natural guide star WFS. We model these LGS aberrations. c © 2007 Optical Society of America OCIS codes: (010.1080) Adaptive optics;(010.7350) Wave-front sensing.

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 کاملShack-Hartmann wavefront sensing using interferometric focusing of light onto guide-stars.
Optical microscopy provides noninvasive imaging of biological tissues at subcellular level. The optical aberrations induced by the inhomogeneous refractive index of biological samples limits the resolution and can decrease the penetration depth. To compensate refractive aberrations, adaptive optics with Shack-Hartmann wavefront sensing has been used in microscopes. Wavefront measurement require...
متن کاملRadial thresholding to mitigate Laser–Guide–Star aberrations on Centre–of–Gravity–based Shack–Hartmann wavefront sensors
Sodium Laser Guide Stars (LGSs) are elongated sources due to the thickness and the finite distance of the sodium layer. The fluctuations of the sodium layer altitude and atom density profile induce errors on centroid measurements of elongated spots, and generate spurious optical aberrations in closed–loop adaptive optics (AO) systems. According to an analytical model and experimental results ob...
متن کاملLive imaging using adaptive optics with fluorescent protein guide-stars
Spatially and temporally dependent optical aberrations induced by the inhomogeneous refractive index of live samples limit the resolution of live dynamic imaging. We introduce an adaptive optical microscope with a direct wavefront sensing method using a Shack-Hartmann wavefront sensor and fluorescent protein guide-stars for live imaging. The results of imaging Drosophila embryos demonstrate its...
