Abstract

We present 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 is 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.
