N2 - The degradation of telescope image quality caused by atmospheric turbulence is currently an important factor restricting the high-resolution observation capability of ground-based astronomical telescopes. Measuring and calculating the effect of the atmosphere on telescope image quality is an important research direction in the field of astronomical technology. Firstly, the theoretical basis for measuring the effect of the atmosphere on image quality using optical and non-optical methods was elaborated, and representative technical routes, measurement results, and research progress of the two measurement methods were presented. The advantages and disadvantages of these measurement methods were analyzed in depth. Then, the basic principles and applicable ranges of three methods for calculating the effect of the telescope's internal airflow on the image quality of telescopes were summarized, and the advantages and disadvantages of these calculation methods were analyzed in depth. Finally, the technical characteristics of optical and non-optical measurement methods and computational methods were summarized, and an outlook on the future development direction of calculation methods was provided.
