Abstract

Techniques for imaging are disclosed. In one example, the disclosure is directed to a sensor positioned on an elongate optical fiber. The sensor comprises a plurality of blazed Bragg gratings configured to generate acoustic energy for imaging a region in response to a first optical signal, an interferometer configured to sense acoustic energy from the region and to provide a responsive second optical signal, the interferometer including a first fiber Bragg grating (FBG) and a second FBG, wherein the plurality of blazed Bragg gratings are positioned between the first and second FBGs.
