ABSTRACT=<p>Holographic display is an ultimate three-dimensional (3D) display technique that can produce the wavefront of 3D objects. The dynamic holographic display usually requires a spatial light modulator (SLM) with a following 4<italic>f</italic> system to eliminate the unnecessary orders produced by the grating structure of the SLM. We present a technique that displays the images without the 4<italic>f</italic> system. We detect the unnecessary wavefield by phase-shifting holography and suppress it using computational optimization. Experimental results are presented to verify the proposed method.</p>
