Abstract

Cameras with extreme speeds are enabling technologies in both fundamental and applied sciences. However, existing ultrafast cameras are incapable of coping with extended three-dimensional scenes. To address this unmet need, we developed a new category of computational ultrafast imaging technique, light field tomography (LIFT), which can perform three-dimensional 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. We demonstrated the proof of concept through light-in-flight imaging of a helical-shaped diffused fiber. The advantage of such recordings is that even visually simple systems can be scientifically interesting when they are captured three-dimensionally at such a high speed. The ability to film the propagation of light through a curved optical path, for example, could inform the design of invisibility cloaks and other optical metamaterials.
