English, We study the diffraction properties of time-and-space domain holograms stored with femtosecond light pulses with a coherence length much smaller than the lateral geometrical dimension of the hole-burning sample. We show that one can observe diffraction of read out beam on the virtual 'time edge' separating the spatial regions where the delay between the reference and the object pulses is either positive or negative. We also demonstrate that by placing a Fourier-transforming lens in the beam diffracted from the 'time edge' a spatial intensity pattern proportional to the homogeneous hole-burning spectrum is observed.
