... modulation refreshing rate can be obtain by using two lines LC SLM and switching from one line to the other. For AOPDF, the acoustic wave is moving at 720m/s in the crystal. Therefore, the acoustic ... SLM, the pixel pitch is 100 μm and the gap 2μm, the thickness is about 10 m. Without taking into account the anisotropy, the smoothing is about 1/20 of the pixel pitch independantly of the gap ... the lateral dispersion of the lenses and gratings is such that the mask can accommodate the entire bandwidth of the input pulse. The “mask bandwidth” depends upon the width of the mask L, the...
