A method for modeling ground based astronomical optical systems using the polynomials of Zernike is described with a focus on large baseline optical interferometers. The effect of atmospheric turbulence is modeled by using the temporal power spectrum of each coefficient. If the polynomials are used to represent physical path-length, rather than phase, the modeling of atmospheric aberrations and many parts of the optical system can be done independently of wavelength. This technique does not require the calculation of large phase-screens nor the choice of pixel size and number in advance. Techniques for modeling tip/tilt systems, mirror surface errors, sub-apertures and calculating visibilities and Strehl ratios are also given.
