SEOUL, South Korea, Jan. 17, 2022 — Researchers at the Korea Institute of Science and Technology (KIST) and Yonsei University are laying the groundwork for 3D digital holography on mobile devices. The group designed a photodiode that detects the polarization of light in the near-infrared region without the need for additional filters. Using this device, the researchers demonstrated miniaturized holographic image sensors for 3D digital holograms. Further research could lead to the miniaturization of the entire holographic camera sensor module — a step that the researchers say opens the possibility of displaying 3D...Read full articleRelated content from Photonics MediaARTICLESPerovskite Optoelectronic Logic Gates Activate Sensor PlatformsResearchers at the Korea Institute of Science and Technology (KIST) and the Gwangju Institute of Science and Technology (GIST) designed an optoelectronic logic gate (OELG) made from organic-inorganic...Photonics.com 5/16/2022Smart Device-Enabled Optical Breathalyzer Checks Blood Alcohol LevelsResearchers at Laval University are developing an optical breathalyzer that can be integrated into the screen of a mobile device.
