Cutting-edge computer-generated holography (CGH) algorithms have realized significant advancements in reconstructing the desired light field, enabling the creation of 4D light field holograms. These holograms offer view-dependent effects, such as motion parallax, occlusion, and specular reflections, which are crucial for enhancing the perceptual realism of 3D scenes. Our holographic display prototype leverages sophisticated CGH algorithms in conjunction with a high-speed binary spatial light modulator (SLM) to deliver an immersive experience of 4D light field holograms. This demonstration highlights the latest progress in CGH technology and emphasizes the critical role of parallax cues in providing perceptually realistic 3D contents.
