flying almost straight up from Vandenberg.

basking in incoming ultraviolet radiation from the sun.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.
