摘要：
In this paper we examine the accuracy with which Zernike coefficients for turbulence-induced wavefront aberrations can be estimated from conventional and Hartmann-sensor images. The performance limit for the estimation of the first 30 Zernike coefficients with a conventional image is shown to be significantly better than the performance limit of an 8 x 8 Hartmann sensor array.
