Abstract
In this paper, facing the high-contrast, high-resolution and high-sensitivity technical difficulties that need to be solvedfordirect detection of habitable exoplanets, we research on the high-precision simulation method of spatial distributedsynthetic aperture optical interference system, which is one of the main ways to achieve this detection goal, by ZEMAXsoftware. We have built the simulation model of optical system for Michelson-type synthetic aperture telescope. It isverified from the principle and simulation analysis in ZEMAX software that the simulation precision of the optical system can achieve a high-contrast better than 10-7, and the simulation results of the distribution and variationof theinterference fringes are correct. Finally, we analyze the influence of factors such as band width and optical systemerroron the key index of the fringe visibility. The research in this paper can provide the necessary foundationfor theparameter decomposition and optimization design of the future spatial distributed synthetic aperture optical interferencesystem in habitable exoplanets.
