Interesting report on the multiplexing of holograms on the back-end of geoengineering

Abstract:

An innovative technique for generating a three dimensional holographic display using strontium barium niobate SBN is discussed. The resultant image is a hologram that can be viewed in real time over a wide perspective or field of view FOV. The holographic image is free from system-induced aberrations and has a uniform, high quality over the entire FOV. The enhanced image quality results from using a phase conjugate read beam generated from a second photorefractive crystal acting as a double pumped phase conjugate mirror DPPCM. Multiple three dimensional images have been stored in the crystal via wavelength multiplexing.

I see they finally resurrected the old Bell Laboratories’ invention from the 1960’s…
