Abstract: An active noise control system is provided with a plurality of error sensor arrays (50, 77) which provide signals on lines (64-74, 90-100) to beam forming and beam steering logic (76) which cause the arrays (50, 77) to exhibit acoustic response profiles (104, 106), respectively. The profiles (104, 106) intersect in a predefined region (116) to be quieted. The logic (76) provides signals on lines (118), one for each region to be quieted, to active noise control (ANC) logic (20) which also receives inputs from feedforward sensing microphones (10) and provides output signals to acoustic speakers (24) which generate anti-noise (26) to cancel the noise in the quiet region (116). The quiet region (116) may be selectively positioned to any region in the room by steering the beams (104, 108). Alternatively, the system may have a plurality of distributed sensors which, when taken together, have an overall maximum (main lobe) acoustic response at a predetermined selectable quiet region.

Abstract: An engine case (20) of a gas turbine engine (10) is selectively coated with a thermal barrier coating (60) to control axial clearance between rotating (22) and stationary (24) airfoils. The coating (60) is applied to the thinner portions of the engine case (20) to retard thermal expansion of these portions of the engine case during transient conditions of the gas turbine engine operation. The selectively coated engine case responds substantially uniformly to heating and thermal expansion during transient conditions, thereby reducing axial vane (24) lean in gas turbine engines.

Abstract: A dual-wavelength pumped low noise fiber laser includes a fiber laser (10) comprising a pair of Bragg gratings (14, 16) at opposite ends of a fiber laser cavity (18) which is co-doped with two rare-earth dopants, Er Yb , so as to allow lasing to occur at a lasing wavelength lambda L. A first pump signal (20) efficiently pumps the Yb to the excited state and the Yb energy is transitioned to the Er atoms which ultimately lase at the desire lasing frequency. Because Yb is pumped so efficiently, high pump absorption is achieved, thereby providing high laser output power and, consequently, reduced RIN. Simultaneously, a second pump signal (52) directly pumps the Er at a different wavelength lambda P2 which populates the lasing transition more quickly, thereby allowing sufficient bandwidth of a closed loop control on the second pump signal (52) to control low frequency RIN spiking due to relaxation oscillations in the laser.

Abstract: A polarized fiber laser source includes a fiber laser (10) comprising a pair of Bragg gratings (14, 16) at opposite ends of a fiber laser cavity (18) which is doped with a rare-earth dopant so as to allow lasing to occur at a lasing wavelength lambda L. A grating tap (26) is provided along a portion of the laser cavity (18) to couple-out a predetermined amount of light along one polarization, e.g., the "s" polarization, at the lasing wavelength lambda L. This causes one polarization mode to experience more loss than the other, thereby allowing the fiber laser to lase only on the less lossy polarization mode and causing the laser output light (40) to be polarized only along such polarization.

Abstract: An optical corrosion sensor employs an optical fiber Bragg grating (20) embedded within an optical fiber (18). The grating (20) has a coating (40) made of a material, such as aluminum, which corrodes or can otherwise be removed. The coating (40) exerts forces (46) radially inward around and along the grating (20) so as to cause the wavelength bandwidth of the grating reflectivity profile to become broader and to be shifted relative to its uncoated condition. Also, the forces on the grating (20) are reduced when the coating corrodes, thereby causing the wavelength bandwidth and shift of the reflectivity profile of the grating to narrow and to return to its uncoated condition.
