Holography is one of the best techniques to generate 3D images. When this technique is applied to a 3D video system, even for a display dimension of 100 mm×100 mm, transmission capacity of more than 10 Gbps would be required. The present digital transmission technique is inappropriate for this application. On the other hand, currently, space-to-time conversion paradigm has attracted a great deal of attention for its ability to convert spatial information into temporal information. In this paradigm a femtosecond optical pulse is spatially dispersed into individual temporal spectrum components and modulated by a row of the hologram generating holographic 3D images. After that various spectrum components are reassembled into a single collimated beam and transmitted as temporal information. The pulse can get one row of the holography instantly. However, a femtosecond pulse light source costs much and the system becomes large. Moreover, the pulse suffers group velocity dispersion and nonlinear effect during optical fiber transmission. In this paper, we applied a super-luminescence-diode (SLD) to this paradigm.
