The past two decades have seen remarkable growth in the capabilities and performance of adaptive optics (AO) systems. These opto-mechanical systems actively compensate for the blurring effect of the Earth's turbulent atmosphere. By sensing, and correcting, wavefront distortion introduced by atmospheric...
The paper concludes with a discussion of some of the challenges related to current and future AO systems, particularly those that will equip the next generation of large, ground-based optical and infrared telescopes. 展开 关键词: Atmospheric effects Instrumentation: adaptive optics Instrumentation: ...
Adaptive optics (AO) systems are an essential part of large astronomical telescopes and laser com- plexes operating through the atmosphere. Each AO system is individually designed; the requirements for the components and the performance of an AO system are determined by the intensity and distribution...
There are also many adaptive optics systems in use for astronomy. Practically all of the new, 8-m class telescopes have adaptive optics and AO systems are being retrofitted to many 4-m class instruments. Examples of systems in regular use for astronomical research include the Very Large Telescop...
In atmospheric laser communications, system performance is influenced by phase disturbance and irradiance fluctuation induced by turbulence and the problem may be solved partly by using adaptive optics compensation. The effect of atmospheric turbulences on uplink and downlink is mitigated in theory and ex...
To tackle this issue, researchers have ventured into advanced techniques such as multi-conjugate adaptive optics and ground-layer adaptive optics28,29,30, using multiple wavefront sensors to broaden the sensing field to approximately one arcminute. However, extending the field beyond this scale while...
