Hee-Jin Choi

Hee-Jin Choi is a Professor at Sejong University's Department of Physics and Astronomy, where he leads the Future Display Lab. He earned his B.S. (2002), M.S. (2004), and Ph.D. (2008) from Seoul National University. His professional experience includes roles at Samsung Electronics (2007-2010) and Schepens Eye Research Institute, a Harvard Medical School affiliate (2016-2017).

Research Focus: Prof. Choi specializes in immersive display technologies including lightfield/holography systems, AR/MR/VR interfaces, and human visual perception. His work addresses critical challenges like visual fatigue compensation, depth perception enhancement, and optical system miniaturization.

Publication Trends: Recent work (2022-2025) focuses on near-eye displays with adaptive pupil compensation, geometric phase optics for AR, and holographic occlusion processing. Earlier research (2014-2020) established foundations in autostereoscopy, integral imaging, and human-factor optimization for 3D displays.

Patents & Innovations: Holds 25+ patents including:

• Adaptive pinhole array NED for pupil variance (2024)
• Geometric-phase-lens AR displays (2020)
• 360° multi-view capture systems (2019)
• Automotive HUD controls (2016)

Academic Service: Regularly presents at major conferences including OSA Digital Holography, SPIE Optics+Photonics, and SID Display Week. Teaches courses like General Physics II and Graduation Research at Sejong University.
