摘要	Most computer-aided alignment methods for optical systems are based on numerical algorithms at present, which omit aberration theory. This paper presents a novel alignment algorithm for three-mirror anastigmatic (TMA) telescopes using Nodal Aberration Theory (NAT). The aberration field decenter vectors and boresight error of misaligned TMA telescopes are derived. Two alignment models based on 3rd and 5th order NAT are established successively and compared in the same alignment example. It is found that the average and the maximum RMS wavefront errors in the whole field of view of 0.3 degrees x 0.15 degrees are 0.063 lambda (lambda = 1 mu m) and 0.068 lambda respectively after the 4th alignment action with the 3rd order model, and 0.011 lambda and 0.025 lambda (nominal values) respectively after the 3rd alignment action with the 5th order model. Monte-Carlo alignment simulations are carried out with the 5th order model. It shows that the 5th order model still has good performance even when the misalignment variables are large (-1 mm <= linear misalignment <= 1 mm, -0.1 degrees <= angular misalignment <= 0.1 degrees), and multiple iterative alignments are needed when the misalignment variables increase.
