Abstract
Based on our previous work (Teng et al., Optics Communication 285, 4235, 2012, [7]), an interactive holographic three-dimensional display system is developed through separating the mirror-image's Fourier CGH of the target object from the planar mirror spatially. A fiber tip is introduced to indicate the spatial content of the displayed light field. Combining with a popup menu, interactive display is realized with the fiber tip as a spatial mouse. The complex amplitude of the zero-order beam caused by the pixelated phase-only spatial light modulator (SLM) is measured through the phase-shifting technology. A hologram which produces not only the functional light patterns but also a corrective beam will be generated to eliminate the zero-order beam through destructive interference. The proposed technology is demonstrated with a 60Hz SLM by introducing an observer tracking unit.
