Fig. 4: Fit providing the reconstruction parameter B from a single-shot recording.
From: Phase Diversity Electro-optic Sampling: A new approach to single-shot terahertz waveform recording
Dots: Fourier spectra \(| {\tilde{Y}}_{1,2}({{\Omega }})|\) of experimental data before reconstruction. Lines: spectra \(| {\tilde{Y}}_{1,2}^{{\rm{retr}}}({{\Omega }})|\) computed from the retrieved input. \({\tilde{Y}}_{1,2}^{{\rm{retr}}}({{\Omega }})\) are fitted on \({\tilde{Y}}_{1,2}({{\Omega }})\) using B as a free parameter. Note the presence of interleaved zeros, which play a key role in the retrieval approach. Same data and color codes as for Fig. 3c, d.
