Abstract

The triple correlation function I⁽³⁾(x₁,x₂) and its Fourier transform, the bispectrum Ĩ⁽³⁾(u₁,u₂), of a one dimensional intensity distribution I(x) are defined by [1], (1) and (2) where Ĩ(u) is the Fourier transform of I(x). Lohmann and Wirnitzer [1] have shown that it is possible to recover a signal I(x) from its triple correlation or bispectrum. The recovered signal is unique except in certain cases of no practical significance in the present study.
