Scientists from South Ural State University (SUSU) in Russia have patented a new technology to prevent PV modules from overheating. Their special technique consists of a holographic film, based on ...

Holography is a process that creates 3D images by “superimposing two light beams onto a physical material.” Developed in the late 1800s by Franco-Luxembourgish physicist Gabriel Lippman ( a man of a ...

An international research team has tested a holographic film based on prismatic concentrators that was presented by Russian scientists last year and is claimed to significantly reduce the operating ...

Holographic polymer films have emerged as a versatile platform where interference patterns are stored via photopolymerisation in photosensitive matrices. When these films are integrated with liquid ...

To make a thin-film hologram, the substrate needs to be rubbery so monomer molecules can travel through it during laser writing. But for the hologram to keep its ability to diffract in the long term, ...
