Abstract:

The authors study the kinetics of nonstationary energy exchange between reconstructing pulses and reconstructed waves in a resonance dynamic hologram. It is shown that the character of energy exchange between a reference beam and reconstructed waves essentially depends on the pulse areas of object beam and reconstructing pulse, their durations, and time lag between them, as well as on the stability of reference wave for small-scale disturbances of its transverse structure. It is found in particular that phase information about the object is distorted due to small-scale instability of the reconstructing pulses, even with no high spatial frequencies in the object spectrum.
