Efficient holographic video generation based on rotational transformation of wavefields
High-quality holographic video generation requires both high computational resources and time; therefore, algorithms that can generate holographic videos efficiently will be soon in demand for dynamic holographic 3D displays. In this work, we present two algorithms that use a motion compensation scheme - based on the rotational transformation of wavefields [Appl. Opt.47, D110 (2008)], to generate efficiently holographic frames. The effects of motions to the wavefield are analyzed, while video generation examples are provided to support our theory. We report that with the proposed motion compensation scheme combined with the Phong multiple wavefront recording plane CGH method, a 10 times acceleration was achieved with regard to the ray tracing method, with a trade-off of energy loss of 10%. This speedup can be further improved by parallelization of the computations.
