Abstract

The gravitational wave detection telescope system is located in a space environment and will be subject to radiation from the sun and Earth, as well as internal thermal power consumption. These factors will cause the gravitational wave detection telescope to be in a changing temperature environment. Due to the effects of structures such as light shields and insulation layers, the temperature environment of the optical system can be equivalent to a steady-state thermal equilibrium environment. Using an optical design software and finite element simulation software combined with an optical mechanical thermal integration design method, simulate the vacuum thermal equilibrium experimental states of the optical system at ambient temperatures of -15 °C, -5 °C, 5 °C, 15 °C, 22 °C, 35 °C, and 45 °C, and analyze the root mean square values of wavefront error, peak valley values of wavefront error, and reference light offset values for different states. At the same time, the vibration experiment of the optical system is simulated, linking mechanical vibration with optical performance analysis indicators, analyzing the PSD response function of mirror deformation RMS value under different working conditions, and the modes that have a significant impact on the composition image of the optical imaging lens.
