摘要	In order to solve the difficulty in the optical testing for large non-circular flat mirrors, we use a non-recursive algorithm based on the inner products of polynomials and the cholesky decomposition methods to complete data processing for the scanning pentaprism system (SPS), and develop the corresponding testing data fitting software. Using the Monte_Carlo technology, we analyze the feasibility for the SPS to test the thirty meter telescope (TMT) tertiary mirror, which is an elliptical flat mirror with size of 2.5 m3.5 m. The simulation results show that the SPS could measure the low order aberrations of this mirror with root mean square (RMS) error of 30.6 nm, especially the power RMS of 9.6 nm and astigmatism of 13.7 nm, which proves the suitability of SPS in testing low order aberrations of large non-circular pupil optical flat mirrors.
