| Abstract: | Technology for all-around holographic three-dimensional (3D) light field display is proposed in this paper. A plane mirror keeps rotating around the optical axis. At each angular position, the mirror-image's Fourier CGH of the target object is projected onto the mirror. The reflected CGH contributes a specific viewing angle range to the target object. Linking up all viewing angle ranges in the horizontal plane, all-around display can be realized via the “afterimage” effect. An all-around holographic 3D light field display is implemented experimentally here with a 60 Hz SLM by introducing an observer tracking unit in the proposed display system. |
