Abstract
A fiber optic acoustic sensor and a method of using same. The sensor includes a light emitting diode and a fiber optic probe having a transmitting multimode optical fiber and at least one receiving multimode optical fiber. The transmitting multimode optical fiber and the receiving multimode optical fiber are substantially parallel to a longitudinal axis of the probe. The fiber optic probe communicates with the light emitting diode. The sensor further includes a cantilever, which includes a cantilever rod. The cantilever rod includes a proximal end with an edge reflector located thereon. The edge reflector is spaced apart from the fiber probe and oriented to face said fiber probe. The edge reflector is able to move in a direction substantially perpendicular to the longitudinal axis of the fiber optic probe. The sensor further includes a light intensity detector communicating with the fiber optic probe.
