Abstract: A fiber optic microphone is provided for measuring fluctuating pressures. An optical fiber probe having at least one transmitting fiber for transmitting light to a pressure-sensing membrane and at least one receiving fiber for receiving light reflected from a stretched membrane is provided. The pressure-sensing membrane may be stretched for high frequency response. Further, a reflecting surface of the pressure-sensing membrane may have dimensions which substantially correspond to dimensions of a cross section of the optical fiber probe. Further, the fiber optic microphone can be made of materials for use in high temperature environments, for example greater than 1000.degree. F. A fiber optic probe is also provided with a backplate for damping membrane motion. The backplate further provides a means for on-line calibration of the microphone.

Abstract: An improved bifurcated multi-lever fiber optic transducer comprising one ht transmitting fiber and two receive fibers having different core diameters separated at one end and combined at the common distal end in the vicinity of a reflective surface parallel to the fiber end plane which is sensitive to axial motion caused by minute pressure changes, either in air or water, such that any displacement of the reflector from equilibrium will increase or decrease the illuminated areas of the two receive fibers which can be used to generate a processed output signal proportional to this motion. The resulting probe is of minimal diameter, has significantly improved sensitivity and produces an output independent of power variations at the input.

Abstract: An apparatus for continuously monitoring changes in a liquid level in accance with a differential pressure is provided. A sensor body immersed in the liquid supports two thin-filmed metallic diaphragms that are independently, axially responsive to pressure of the liquid. Each diaphragm has a different modulus of elasticity. Two fiber optic pressure sensors are mounted within an air space encased by the sensor body in combination with the two diaphragms. Each of the two fiber optic pressure sensors detects the axial response of one of the two diaphragms. The displacement difference between the two diaphragms is an indication of differential pressure related to the liquid level.

Abstract: A small diameter towed acoustic line array comprising a plurality of miniature fiber optic lever hydrophones spaced at preselected locations along the array and held in place by fiber holders. The array hydrophones are enclosed within a tubular outer sheath which is filled with an acoustically transparent fluid. The hydrophones respond to either the pressure mode or the pressure gradient mode, each hydrophone further comprising at least one receiving and one transmitting optic fiber of the same diameter, a covering sheath, a clear elastomer and a small reflector. The information received is transmitted to and processed by a beamformer external to the array.

Abstract: A method for determining optimum element spacing for a low frequency, log-periodic acoustic line array comprising a plurality of omnidirectional hydrophones arranged in a line wherein the spacing between hydrophones is based on a logarithmic relationship using multiple dipole pairs, each pair centered about the acoustic axis of the array, such that the distance between each dipole pair bears a constant ratio to the wavelength of the acoustic frequency band to be investigated by that hydrophone pair. Each dipole pair relates to a particular frequency band and the assembled array covers at least a decade range of frequencies through juxtaposition of contiguous frequency bands. The overall arrangement assures retention of selected beam pattern directionality over the entire decade range of frequencies.
