Abstract

Mirror and dome seeing are critical effects influencing the optical performance of ground based telescopes. The Thirty Meter Telescope project has been utilizing a combination of optical simulations and Computational Fluid Dynamics to model the dome and mirror seeing. A set of optical modeling tools has been developed in MATLAB to post-process high spatial resolution thermal CFD results and calculate image degradation due to dome seeing and mirror seeing. The same tools can provide the distribution of seeing contribution along optical path in order to recognize potential problems and guide the observatory design. The method, including limiting assumptions for the optical modeling tools are discussed.
