利用夏克-哈特曼波前传感器检测相位奇异点

Detection of phase singularities with a Shack-Hartmann wavefront sensor

Mingzhou Chen, Filippus S. Roux, Jan C. Olivier

摘要:

虽然自适应光学系统能够去除偏振光束中的适度波前畸变,但出现在强偏振光束中的相位奇异性会严重降低这种自适应光学系统的性能。因此,探测这些相位奇异性是强闪烁自适应光学的一个重要方面。我们调查的相位奇点的检测与援助的夏克-哈特曼波前传感器,并表明,尽管一些系统的缺陷固有的夏克-哈特曼波前传感器,它可以用于可靠的检测相位奇点,无论其形态。我们提供了完整的分析结果,以及检测过程的数值模拟。

英文摘要:

While adaptive optical systems are able to remove moderate wavefront distortions in scintillated optical beams, phase singularities that appear in strongly scintillated beams can severely degrade the performance of such an adaptive optical system. Therefore, the detection of these phase singularities is an important aspect of strong scintillation adaptive optics. We investigate the detection of phase singularities with the aid of a Shack-Hartmann wavefront sensor and show that, in spite of some systematical deficiencies inherent to the Shack-Hartmann wavefront sensor, it can be used for the reliable detection of phase singularities, irrespective of their morphologies. We provide full analytical results, together with numerical simulations of the detection process.
