Abstract:

In true-3D systems, there is no restriction on the observer side since they ideally reproduce the exact field of the volume filling light with all relevant physical properties. Holography is also a sophisticated true-3D technique. Electro-holography is used to display dynamic holograms. Spatial light modulators are commonly used in electro-holographic systems to display such holograms. A single spatial light modulator is inadequate for a satisfactory quality display. Our study shows that using multiple spatial light modulators is a good solution to achieve satisfactory quality holographic display system. Understanding the single spatial light modulator designs is crucial before moving to multiple spatial light modulators. Color holographic displays, real-time holographic displays, planar and circularly configured holographic displays are some of the multiple spatial light modulator holographic display systems. All of the results point out that the circularly configured holographic display systems are superior and desirable.
