Abstract：Since the first discovery of exoplanets in the 1990s,the techniques for exoplanet detection have experienced a rapid development.To date,over 5 500 exoplanets have been detected,including various types such as terrestrial planets,super-Earths,gas giants and ice giants.These discoveries have profoundly expanded our understanding of the universe,providing invaluable observational data for comprehending planetary formation and evolution,and offering crucial clues in the search for habitable planets and extraterrestrial life.This paper aims to compare and analyze the technical characteristics of different detection methods by introducing the various core technologies employed in exoplanet detection,including their principles and application characteristics.Furthermore,by analyzing the advantages and limitations of each detection technique,this paper provides practical references and insights of future trends for exoplanets'measurement and survey.
