Seeing Improvement with Ground-Layer Adaptive Optics
Ground-layer adaptive optics (GLAO) promises a significant improvement in image width and energy concentration over atmospheric seeing in a relatively wide field by compensating for low-altitude turbulence only. This approach, which is intermediate between full AO and seeing-limited observations, can benefit many astronomical programs in the visible and near-infrared. We have developed a simple...
متن کاملGround Layer Adaptive Optics Performance in Antarctica
Ground layer Adaptive Optics (GLAO) is a new variant of adaptive optics that aims at correcting the seeing over a wide field of view by conjugating the deformable mirror to the boundary layer altitude.The South Pole is expected to be particularly to GLAO due to the absence of high altitude jets and the confinement of 96% of the seeing within a 220 m boundary layer. We present here the compariso...
متن کاملGround-Layer Adaptive Optics with Multiple Laser Guide Stars
We report the first closed-loop results obtained from an adaptive optics system with multiple laser guide beacons. The system is mounted on the 6.5 m MMT in Arizona, and is designed to explore advanced altitude-conjugated techniques for wide-field image compensation. Five beacons are made by Rayleigh scattering of laser beams at 532 nm integrated over a range from 20 to 29 km by dynamic refocus...
متن کاملEnhancing image quality in cleared tissue with adaptive optics.
Our ability to see fine detail at depth in tissues is limited by scattering and other refractive characteristics of the tissue. For fixed tissue, we can limit scattering with a variety of clearing protocols. This allows us to see deeper but not necessarily clearer. Refractive aberrations caused by the bulk index of refraction of the tissue and its variations continue to limit our ability to see...
متن کاملOvercoming the Boundary Layer Turbulence at Dome C: Ground-Layer Adaptive Optics versus Tower
The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are very favorable for high spatial resolution astronomy. At Dome C, the majority of the optical turbulence is confined to a 30 to 40 m thick stable boundary layer that results from the strong temperature inversion created by the heat exchange between the air and the ice-covered ground. To fully realize t...
