A Review of Exoplanet Detection Telescopes: Performance Design and Technology Optimization

Exoplanets are regarded as important objects for studying stellar evolution and also as the basis for exploring the origin of life. Therefore, they have been one of the hotspots in astronomical research for many years. Since 1992, thanks to the improvement in the precision of astronomical observation equipment, more than five thousand exoplanets have been discovered. In recent years, the progress in ground-based and space-based observation technologies has significantly enhanced the precision and efficiency of detection and promoted the implementation of more ground-based detection projects. This paper introduces the existing exoplanet detection telescopes and their representative instruments, summarizes the progress in telescope technology and hardware optimization, and looks forward to the research and development trends in the next 5 to 10 years.
