This paper describes an alignment technique using an optical design program and an interferogram analysis code. The method is demonstrated on a two-mirror telescope. Instead of minimizing a merit function, which is normally composed of the designed system aberrations, a 'de-merit' function is constructed from the coefficients of the measured aberration function of an assembled (misaligned) system. The interferogram analysis program fits the aberration function to a Zernike polynomial expansion. The optimization routine of the optical design program is instructed to reproduce these coefficients using only the alignment parameters of the secondary mirror (tilt, decenter and air space) as degrees of freedom. At the final stage, the program produces the actual misalignment parameters. In the experiments described here, real interferograms were not used, but simulated systems were analyzed.
