本文介绍了用于高对比度冠脉造影术的基于像面强度测量的复电场重建方法。可变形镜(DM)表面用一对互补形状进行修改，以在测量光强度的科学相机的图像平面中产生多样性。与电场共轭校正算法一起，这种估计方法已被用于各种高对比度成像试验台，以获得迄今为止在窄带和宽带光中的最佳对比度。我们在简单的步骤列表中介绍了估计的基本方法，给出了来自HCIT的结果，并提出了使用该方法所面临的几个公开问题。
In this paper we describe the complex electric field reconstruction from image plane intensity measurements for high contrast coronagraphic imaging. A deformable mirror (DM) surface is modified with pairs of complementary shapes to create diversity in the image plane of the science camera where the intensity of the light is measured. Along with the Electric Field Conjugation correction algorithm, this estimation method has been used in various high contrast imaging testbeds to achieve the best contrasts to date both in narrow and in broad band light. We present the basic methodology of estimation in easy to follow list of steps, present results from HCIT and raise several open questions we are confronted with using this method.
