摘要：
The accuracy of an interference measurement experiment depends on the conditions of the fringe pattern formation. This work is a study into the influence of the Gaussian inhomogeneity of a laser beam on the error of the wavefront reconstruction. The illuminating laser beam is represented as a Gaussian model. It has been demonstrated that the efficient size of the laser beam influences the measurement error, and this effect is the most pronounced in evaluation of the interferograms with a small number of fringes, especially during high-precision measurements.
