摘要：
Fiber-optic acoustic sensors having sensitivity nearly 2 orders of magnitude greater than that of sensors using bare fiber are reported. These new devices utilize a composite structure wherein the fiber is embedded in a material of lower elastic modulus that serves to increase the stress, and hence the optical phase shift, in the fiber for a given pressure. © 1979, Optical Society of America.
