AbstractSite test ing results indicate thal Antarctic Dome A is an excellent ground-based astronomical sile sui table for observations ranging from visible to infrared wavelengths. However, the harsh environment in Antarctica, especially the very low temperature and atmospheric pressure, always produces frost on the telescopes' mirrors, which are exposed to the air. Since the Dome A site is still unattended, the Antarctic telescope tubes are always designed to be filled with dry nitrogen, and the outer surfaces of the oplical system are heated by an indium-tin oxide thin film. These precautions can prevent optical surfaces from frosting over, but they degrade the image quality by introducing additional rnirror seeing. Based on testing observations of the second Antarctic Survey Telescope (AST3-2) in the Mohe site in China, rnirror seeing resulting from the heated aspheric plate has been rneasured using micro-thennal sensors. Results comparing the real-time atmospheric seeing monitored by Ihe Differenlial Image Motion Monitor and real-time exarninations of image quality agree well.
