Abstract
A series of simulations were made for an ideal Twyman-Green interferog ram of equally spaced straight fringes having tilt only about x. It wa s found that fitting polynomials to the interferometric data resulted in biased estimates of some of the fitting coefficients to the optical path difference. The acceptance of the Seidel aberrations grows with the noise level and diminishes when the number of fringes is increased .
