abstract = "We describe a method for measuring and aligning phase parameters with Zernike polynomials in large segmented-mirror telescope system. Numerical model is developed to establish the dependence of tip-tilt phase parameters on the polynomial coefficients C1 and C2 and know the real displacement direction though the measurement and calculation of Zernike polynomials. Its performance is analytically examined in detail and some experimental results demonstrating its effectiveness are also given. This method extremely simplified the segment phase adjustment process to a certainty. The measurement result proved that the tilt is 15λ and the tip is 7λ (λ=633nm), showing that the precision is about to nanometer level.",
