High-speed 3D Structured Light Imaging and Applications
Advances in optical imaging and machine/computer vision could have profound impact on biomedical engineering. My research addresses the challenges in high-speed, high-resolution 3D imaging and optical information processing. My current research focuses on achieving speed breakthroughs by developing the binary defocusing techniques; effectively storing enormously large 3D data by innovating geometry/video compression methods; and automating structured light 3D microscopic imaging techniques using the recently developed electrically tunable lens (ETL). The binary defocusing methods coincide with the inherent operation mechanism of the digital-light-processing (DLP) technology, permitting tens of kHz 3D imaging speed at camera pixel spatial resolution. The novel methods of converting 3D data to regular 2D counterparts offer us the opportunity to leverage mature 2D data compression platform, achieving extremely high compression ratios without reinventing the whole data compression infrastructure. The electronically controllability of ETL lens shows promise for large Field of View (FOV) 3D imaging automation. In this talk, I will present our recent work in these areas and discuss some of the applications that we have been exploring including biomedical engineering, forensic sciences, along with others.
