iPhone owners had reported finding either no data or old cached weather information on the Weather appand improve holography-based optical encryption by allowing more data to be encrypted in the hologram.

” The researchers used a diffuser to separate multiple image planes by a smaller amount without being constrained by the properties of a spatial light modulator (SLM).the researchers were able to project a 3D rocket model with 125 successive image planes at a depth interval of 0.the new ultrahigh-density method “overcomes two long-existing bottlenecks in current digital holographic techniques — low axial resolution and high interplane crosstalk — that prevent fine depth control of the hologram and thus limit the quality of the 3D display.

 The study on the ultrahigh-density method for producing realistic holograms was published in the peer-reviewed journal Optica.The researchers also built a prototype 3D-SDH projector and compared it directly to another state-of-the-art method known as 3D Fresnel computer-generated holography.

the team developed a new approach to holography that overcame some of the long-standing limitations of current digital holographic techniques.

The researchers noted that all of the holograms they demonstrated in their experiments were point-cloud images.TSMC plans to establish a second fab in Kumamoto.
