摘要	In this paper, a laser communication antenna with two mirrors is designed. The decenters of the secondary mirror do not introduce field-linear coma, which reduces the antenna's sensitivity to misalignment, and we call it coma insensitive system. The conic coefficients of the primary and secondary mirrors of the coma insensitive system are different from those of the Cassegrain and RitcheyChretien systems. We derive the calculation formula of the coma insensitive system in detail based on the nodal aberration theory. Through a design example, the performance of the coma insensitive, Cassegrain and RitcheyChretien system in the nominal state and the secondary mirror decentered state is compared, and it is found that the aberration performance of the Cassegrain and RitcheyChretien system in the nominal state is much better than that of coma insensitive system. However, when the secondary mirror is decentered, the performance of Cassegrain and RitcheyChretien system is obviously inferior to coma insensitive system, and their rms spot diameter is about 2.8 times that of coma insensitive system. 2022, The Optical Society of India.
