Event Poster


In the recent Consumer Electronics Show (CES), 3D display attracts much attention from both the industry and academia. However, current display technology with the lightweight optics do not scale to provide resolution, field of view (FOV) and depth cues on par with human visual acuity. Owing to the advance in faster electronics and digital processing power, digital holography may solve the challenge in the passive optical device by computational solutions.

Theoretically, Digital holography offers efficient wavefront encoding by holographic superposition and smooth wavefront control. Unfortunately, it is not generally available for the device which is capable of modulating both amplitude and phase of a wavefront. Availability aside, phase-only spatial light modulators (SLMs) are often preferred because of the high light efficiency. Therefore, how to deal with the amplitude needs to be addressed in the calculation of phase-only holograms. Rong will go through the principle of holographic display, 2D/3D algorithm in phase-only holograms ant typical applications as well as other related topics in 3D displays.
