We propose an easy method for unknown wavefront reconstruction by a typical Fourier transform system based on an amplitude-only spatial light modulator (SLM). The Fourier transform of the diffraction intensity pattern on the backfocal plane is the autocorrelation of the wavefront-transmitted SLM. Tw...
