| 英文摘要 | To carry out the error analysis and allocation for large optical systems, on the basis of the "normalized Point Source Sensitivity"(PSSn) proposed by the TMT primary mirror team, the characteristics and distribution of errors of large sparse aperture telescopes were investigated. Firstly, the basic properties of PSSn was studied and its advantages as an all-frequency domain evaluation metric of large sparse aperture telescopes was discussed. After that, the influence of different error sources on large sparse aperture telescopes was analyzed using PSSn. PSSn at different evaluation scales was analyzed. Finally, based on the relationship between the PSSn and slope root mean square, an error model using the "Brownian Bridge" walk and PSSn was proposed, considering the closure characteristics of the position error between the mirrors. The work has guiding significance for the design and testing of a similar large telescope system. 2019, China Science Publishing & Media LTD. All right reserved. |
