reects the entire Gaussian spectrum of the source while the sec-
ond sample surface absorbs the high-frequency portion (upper
half) of the source spectrum. is simulation is analogous to
the absorption phantom experiment discussed in Section 23.4.3
and illustrated in Figure 23.14. In the scenario of this simula-
tion, that is, an SOCT system, neither the Wigner nor the MH
distributions can be constructed because the detected signal is
the intensity of the eld and therefore the phase information is
lost. us, TFDs are reconstructed via the STFT and the DW
method.
Figure 23.4a through c shows the ideal TFD of t ...
