Abstract

Transient phenomena contain rich intrinsic features as shown in the famous Edgerton's photo of a bullet piercing through an apple with the help of a stroboscope. Although a photo is able to freeze transient phenomena, it still lacks the ability to reveal intrinsic micro motions of constituents. The advancement of optical fibers has changed the above scenario. An RF transient signal and its reference can be fed into optical fiber recirculation loops, which are able to regenerate numerous replicas of these signals. The micro motions captured by the transient signal can then be deciphered through the repeated analysis of its replicas. A new instrument which is capable of accomplishing the above is known as an interferoceiver. It will have a broad impact on radar technology as well as on remote sensing and passive identification. The present talk will discuss its capabilities and experimental results.
