摘要：
The results of an extensive computer simulation study are presented in this paper. Optimal parameter values are determined for previously derived weighted least squares algorithms used to estimate an object's Fourier spectrum from its bispectrum. The relative quality of phase and power spectra estimated from bispectra is discussed, and it is shown that the useful portion of the bispectrum includes elements with offsets larger than the seeing cutoff spatial frequency.
