Smartphone Generated Holograms Are One Sensor Closer

Researchers at the Korea Institute of Science and Technology (KIST) have created 3D digital holograms, by developing a polarisation image sensor with no additional polarisation filter. With the further miniaturisation of the holographic camera sensor module, the researchers believe this could lead to holograms generated by smartphones.

KIST has recently announced that a research team led by Dr. Min-Chul Park and Dr Do Kyung Hwang of the Center for Opto-Electronic Materials and Devices, in collaboration with a research team led by Prof Seongil Im of the Department of Physics at Yonsei University, has successfully developed a photodiode that detects the polarisation of light in the near-infrared region without additional polarisation filters.

With this approach, the team has been able to produce a miniaturised holographic image sensor for 3D digital holograms, using the 2D semiconductor materials rhenium diselenide and tungsten diselenide. The work is published in ACS Nano1.
