Paper Abstract

The detection of exoplanets is a hot topic in international astronomy nowadays. The methods of exoplanets detection are mainly divided into indirect detection and direct imaging. Direct imaging of exoplanets is being pursued by a number of research groups around the world. In this paper, the research status of space-based direct imaging technologies for exoplanets detection is reviewed, and the advantages and disadvantages of related technologies are analyzed and summarized. The most advantageous and promising space-based nulling interferometry technologies are described in detail, including some laboratory verification studies based on ground-based astronomical telescopes. With the continuous development of spacecraft micro-Newton propulsion and high-precision positioning control, ultra-high-precision laser measurement, adaptive optics, integrated optics, etc., space-based direct imaging technologies for exoplanets detection will continue to make breakthroughs.
