摘要
研究了在CP/CM系统中 ,两个哈特曼夏克波前传感器用于控制一套波前校正器件的几种数据融合方法 ,通过复原矩阵的条件数分析了斜率数据向量的扰动和复原矩阵的扰动对系统控制电压的影响 ,得到了相应的公式。实现了CP/CM自适应光学闭环实验 ,并且利用实际系统比较了几种数据融合方法 ,认为现有工程技术条件下 ,加修正因子斜率融合和电压融合是可行的办法 ,二者在控制电压的得到上是等价的 ,不同之处将表现在波前处理机。
In the common path/common mode(CP/CM) adaptive optics(AO) system,two Hartman-Shack (H-S) wavefront sensors are used to realize the aberration sensing in the whole light path,controlling of a set of wavefront corrector and compensation of the aberration in the whole light path. Here the data fusion methods of the two H-S sensors in the CP/CM AO system are studied and the effects of the disturbance of the vector of slope data and the Reconstruction matrix to the controlling voltage are analyzed through the condition number of the reconstruction matrix. Corresponding formula are given. The close loop experiment of CP/CM is achieved. Modified slope and voltage data fusion methods are suitable to the engineering under the existing technology condition. They are equivalent in the finding of the controlling voltage,but the wavefront processors will be different.
