论文摘要
我们介绍了对位于太阳重力透镜产生的外部外球星的真实图像的仪表望远镜对外球星的高分辨率成像的分析。我们假设在整个相位观察的系外行星和一种简单的反卷积方法来校正由太阳重力镜头中的像差引起的固有模糊，并解释了太阳能电晕的前景光。我们得出望远镜产生这样的高分辨率图像所需的测量时间的方程式，并发现由于射击噪声的考虑，这些时间与人类寿命相比很大。我们还讨论了具有特殊轨道和旋转参数的系外行星的测量时间如何显着短。
We present an analysis of high-resolution imaging of an exoplanet by a meter-class telescope positioned at a real image of the exoplanet created by the solar gravity lens. We assume an exoplanet viewed in full phase and a simple deconvolution method to correct for the intrinsic blur caused by aberrations in the solar gravity lens, and account for the foreground light of the solar corona. We derive equations for the measurement times required for the telescope to produce such a high-resolution image, and find that due to shot noise considerations these times are large compared to human lifespans. We also discuss how measurement times could potentially be significantly shorter for exoplanets with special orbital and rotational parameters.
