In this study, it is newly attempted to combine digital holography method to get the holography fringe data using the CCD with the pulsed electro-holographic system for real-time display. Owing to the one-dimensional characteristic of the Bragg regime AOSLM that the fringe data propagating in parallel with the laser incident plane in the crystal cannot diffract the incident reference beam vertically by the momentum conservation, the diffraction of vertical direction from the AOSLM is impossible and the vertical parallax is not generated. Therefore the confocal lens system with a horizontal slit is introduced to obtain proper interference pattern. When the display of pulsed laser electro-holographic system is made by the fringe data of which bandwidth is reduced, the image clearness and quality is more improved than the recorded data without the confocal system with a horizontal slit since the fringe is formed to give mainly the horizontal parallax and the bandwidth of vertical direction is reduced so that the one line of object is projected onto only one line pixels of the CCD at same height.
