|Light transport contains all light information between the light source and the image sensor. As an important application of light transport, dual photography has been a popular research topic, but it is challenged by long acquisition time, low signal-noise ratio, storage and computation of a large number of measurements. In this paper, we propose a novel hardware setup that combines a flying-spot MEMS modulated projector with an event camera to implement dual photography for 3D scanning in both line-of-sight (LoS) and non-line-of-sight (NLoS) scenes with a transparent object. In particular using event light transport, depth extraction from the LoS scenes and 3D reconstruction of the object in a NLoS scene have been achieved.
