Fiber optic cantilever acoustic vector sensor

摘要

An apparatus includes a rigid support and a first cantilever including a first optical fiber and a first rigid ribbon. The first optical fiber and the first ribbon, together include a first neutral surface. The first optical fiber is connected to the rigid support. The first optical fiber includes at least one first wave-guiding core running parallel to the first neutral surface. Each of the at least one first wave-guiding core includes at least one first reflector. The first rigid ribbon is affixed to the first optical fiber and to said first rigid support. The apparatus further includes a first membrane surrounding the first cantilever.
