Single-shot full-field measurement with a multimode fiber (Conference Presentation)
Author(s): Hui Cao

Paper Abstract

Multimode fibers are widely explored for optical communication, imaging and sensing applications. We develop a single-shot full-field temporal measurement technique based on a multimode fiber. The complex spatiotemporal speckle field is created by a reference pulse propagating through the fiber, and it interferes with a signal pulse. From the time-integrated interference pattern, both the amplitude and the phase of the signal are retrieved in spectral and temporal domains. The simplicity and high sensitivity of our scheme illustrate the potential of multimode fibers as versatile and multi-functional sensors.
