Phase-only holographic projection has driven a great deal of research and has often been seen as a desirable method of 2-D image formation. It is superior to conventional imaging projection technology. a real-time 2-D video projection system is developed here using this system. The computational
complexity of calculating diffraction patterns has been the major hindering force for this. The poor quality of the resultant images was also a factor. This paper shows a a new pproach to hologram generation and display. Thus a
high-quality real-time holographic projector is designed.

A HOLOGRAPHIC display employs a phase-modulating display element in combination with a coherent light source to form images by diffraction, rather than projection. The need for polarizers is eliminated alongwith providing high optical efficiency by forming images by routing. The optical wavefront can be controlled completely.

IMPROVED METHOD FOR HOLOGRAM GENERATION
The direct binary search (DBS) and Gerchberg–Saxton (GS) etc are the conventional and currently available algorithms for hologrram formation.
