Abstract

Without decreasing spatial resolution, temporal compressive imaging (TCI) can improve the temporal resolution of an imaging sensor and relax the requirement of the data readout speed in high-speed imaging. In this Letter, we describe a near-infrared TCI system that can reconstruct 500 fps videos from coded measurement frames sampled at 50 fps.
