天文斑点成像中的傅里叶模复原和像复原实验

Fourier Modulus Recovery in Astronomical Speckle Imaging and the Experiments of Image Reconstruction

在天文高分辨率像复原中 ,目标的傅里叶模复原与相位复原同样重要。由于观测数据中存在着多种复杂噪声 ,模和相位的复原将变得更加困难。本文针对在模复原中的各种噪声 ,提出相应的噪声改正方法 ,所给出的像复原实验表明 ,这些方法是有效的和必须的 。

In astronomical high resolution image reconstruction, Fourier modulus recovery is as important as the phase recovery of a object, because there are many kinds of complex noise in observations and the recovery of modulus or phase will become more difficult. To solve the problem of the noise of all kinds in the modulus recovery, some appropriate methods are provided. The experimental results of image reconstruction show that these methods are effective and necessary, they ensured the high precision modulus recovery.
