自适应光学系统校正后实际分辨率评价指标
Evaluation index of the actual resolution after correction of adaptive optical system
摘要
Abstract
A new index, Resolved Cells Ratio ( RCR), was proposed to evaluate the actual resolution of ground-based large-aperture telescope for spatial objective observation after adaptive optical system partial cor -recting .We discussed the physical meaning of the RCR combined with the observation instances of the 1.23 a-daptive optical telescope .The range of the application of the RCR , the error influence factors and the effect of the atmospheric dispersion on the RCR were also analyzed .The result shows that the RCR could completely reflect the correction effectiveness of the adaptive optical telescope and the physical meaning of the RCR was intuitive .RCR can be applied to the estimation of the correction effectiveness of a telescope that can get the characterization of the wavefront .The error of the RCR mainly depend on the measurement error of the wave-front sensor .The effect of atmospheric dispersion on the RCR can be neglected .关键词
