Development of a novel astronomical-image restoration method using parallel wavefront sensors

提出了一种利用自适应光学系统改善部分校正后的太阳图像的图像后处理方法。在我们的方法中，在声光系统中增加了另一个波前传感器，利用外部触发器同时观测太阳图像和波前信息。从波前信息估计PSF，然后对太阳图像进行去卷积以进行改进。我们将我们的方法应用于用日田天文台的无顶太阳望远镜观测到的图像，并证实了良好的复原效果。

We developed an image post-processing method of improving solar images partially-corrected through an adaptive optics (AO) system. In our method, another wavefront sensor is added into the AO system, and a solar image and wavefront information are simultaneously observed using an external trigger. A PSF is estimated from the wavefront information and then the solar image is deconvolved to be improved. We applied our method to images observed with the domeless solar telescope of the Hida Observatory, and confirmed good restoration.
