а) Diffraction efficiency DE <strong>of</strong> each <strong>of</strong> 5 pulsed superimposed holograms during
recording stage (dots, λ rec =532 nm) and stationary DE (columns) measured after recording.
Measurement <strong>of</strong> DE was carried by use <strong>of</strong> He-Ne laser (λ=633 nm).
b) Images <strong>of</strong> objects restored by each <strong>of</strong> 5 superimposed holograms at reading
by radiation <strong>of</strong> the continuous laser (λ=532 nm).
