摘要：

极大望远镜（ELT）的行星照相机和摄谱仪（PCS）将专门用于探测和描述太阳附近大小从亚海王星到地球大小的系外行星。这一目标是通过极限自适应光学（XAO）、日冕照相术和光谱学的组合来实现的。PCS不仅可以让我们拍摄图像，还可以在系外行星的大气层中寻找生物特征，如分子氧。本文介绍了PCS的主要科学目标，仪器的概念和研究和开发活动，将在未来几年内进行。

英文摘要：

The Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will be dedicated to detecting and characterising nearby exoplanets with sizes from sub-Neptune to Earth-size in the neighbourhood of the Sun. This goal is achieved by a combination of eXtreme Adaptive Optics (XAO), coronagraphy and spectroscopy. PCS will allow us not only to take images, but also to look for biosignatures such as molecular oxygen in the exoplanets' atmospheres. This article describes the PCS primary science goals, the instrument concept and the research and development activities that will be carried out over the coming years.
