Abstract

Cameras with extreme speeds are enabling technologies in both fundamental and applied sciences. However, existing ultrafast cameras cannot cope with extended three-dimensional (3D) scenes. To address this unmet need, we developed a new category of computational ultrafast imaging technique, light field tomography (LIFT), which can perform 3D snapshot transient (time-resolved) imaging at an unprecedented frame rate with full-fledged light field imaging capabilities, including depth retrieval, post-capture refocusing, and extended depth of field. As a niche application, we demonstrated real-time non-line-of-sight imaging of fast-moving hidden objects, which was previously impossible without the presented technique. Moreover, we showcased 3D imaging of fiber-guided light propagation along a twisted path and the capability of resolving extended 3D objects. I will also talk about our recent work on applying LIFT to image transient biological events at microscopic scales in this talk.
