光波相位不连续点的探测

Detection of Branch-Point in Light Phase

提出了同时利用哈特曼波前传感器测量的子孔径波前斜率和光强数据进行信标光相位复原的改进算法 ,并在此基础上对实测的斜率数据进行分析。结果表明在强湍流效应情况下 。

An improved algorithm of beacon light phase reconstructed is developed with the data of slope and data of intensity of subaperture measured by Hartmann sensor. This measured data of phase gradient is analyzed based on the improved algorithm. The result shows that there is branch points in beacon light phase in strong scintillation for the measured phase-gradient.
