Paper Abstract

In optical three-dimensional imaging and measurement based on fringe projection, wrapped phases may cause a problem of ambiguity, which can be overcome by phase unwrapping generally. In this paper, a method for absolute phase unwrapping using light-field imaging is reported. In a recorded light field under structured illumination, i.e., a structured light field, a wrapped phase-encoded field was retrieved and resampled in diverse image planes associated with several possible fringe orders in a measurement volume. By leveraging phase consistency constraint, the resampled wrapped phase-encoded field correct fringe orders could be determined to unwrap phase without any additional encoding information.
