The SNU ECE Optical Engineering and Quantum Electronics(OEQE) Laboratory 3D Display Research Team (Advisor: Professor Yoonchan Jeong) suggested the possibility of watching an image with a wider angle of view on a holographic display by utilizing lenslet arrays with converging axes. Unlike conventional methods where the user cannot watch an image under certain conditions such as the position or diameter of his/her pupil, the research team’s proposed an improvement where a small pupil can continuously observe a holographic image. This research was announced in the 2023 IEEE Photonics Conference (November 16th, 2023 / held in Orlando, United States), and was awarded 2nd place in the Best Student Poster Competition.
