摘要： An apparatus for measuring at least one parameter associated with a fluid flowing within a pipe includes a single sheet of piezoelectric film material wrapped around at least a portion of the pipe and an array of sensors disposed at different locations on the film material. Each of the sensors provides a signal indicative of pressure within the pipe at a corresponding axial and/or circumferential location of the pipe. The sensors are selectively configurable to provide the pressure signals. The signals are processed to determine the parameter. The array of sensors is configurable in response to different criteria. The criteria includes at least one of the parameter of the fluid to be output, an input signal specifying sensors to be selected, a predetermined configuration based on the parameter to be determined, and in response to a previously determined parameter of the fluid.

摘要： An optical filter for filtering a spectral profile of an optical signal for providing an output signal having a desire gain profile, such as a flatten gain profile. The filter comprises an optical waveguide that includes a core disposed within a cladding having an outer dimension greater than 0.3 mm. A Bragg grating is imparted or written in the core of the waveguide that attenuates the received optical input signal in accordance with a defined reflection or transmission filter profile. The Bragg grating may be a slanted grating. The filter profile is complementary to the spectral gain profile of the input signal to provide an output signal having a substantially flat spectral profile of a desired wavelength band. The cladding of the waveguide may have a mechanically advantageous outer geometry (e.g., a “dogbone” shape) for allowing an axial compressive force to tune the Bragg grating. The waveguide may be package within an athermal device, which tunes the grating to compensate for temperature dependent changes. Further, the waveguide may be packaged in a tuning device to selective tune the gratings to shift the center wavelength of the spectral profile of the filter, or to change the shape of the filter profile.

摘要： A pressure-isolated Bragg grating temperature sensor includes an optical element, which includes an optical fiber having at least one Bragg grating disposed therein. The Bragg grating is encased within and fused to at least a portion of an inner glass capillary tube, or comprises a large diameter waveguide grating having a core and a wide cladding and having the grating disposed therein, encased within an outer tube to form a chamber. An extended portion of the sensing element that has the grating therein extends inwardly into the chamber, which allows the grating to sense temperature changes but isolates the grating from external pressure. More than one grating or pair of gratings may be used and more than one fiber or optical core may be used. At least a portion of the sensing element may be doped between a pair of gratings to form a temperature tuned laser, or the grating or gratings may be configured as a tunable DFB laser disposed in the sensing element.

摘要： A compression-tuned bragg grating includes a tunable optical element 20,600 which includes either an optical fiber 10 having at least one Bragg grating 12 impressed therein encased within and fused to at least a portion of a glass capillary tube 20or a large diameter waveguide grating 600 having a core and a wide cladding. Light 14 is incident on the grating 12 and light 16 is reflected at a reflection wavelength &lgr;1. The tunable element 20,600 is axially compressed which causes a shift in the reflection wavelength of the grating 12 without buckling the element. The shape of the element may be other geometries (e.g., a “dogbone” shape) and/or more than one grating or pair of gratings may be used and more than one fiber 10 or core 612 may be used. At least a portion of the element may be doped between a pair of gratings 150,152, to form a compression-tuned laser or the grating 12 or gratings 150,152 may be constructed as a tunable DFB laser. Also, the element 20 may have an inner tapered region 22 or tapered (or fluted) sections 27. The compression may be done by a PZT, stepper motor or other actuator or fluid pressure.

摘要： An all fiber wavelength selective optical switch has one or more 1.times.N input optical couplers 20,120, each having an input signal with a plurality of wavelengths .lambda..sub.1, .lambda..sub.2, .lambda..sub.3. The output signals from the couplers 20,120 are connected to fibers 26,32,126,158 having Bragg gratings impressed therein, each having a central reflection wavelength, and each having a tuner attached thereto for detuning a central reflection wavelength of the gratings from a base wavelength corresponding to a wavelength of the input signal. For a given grating to pass a particular wavelength of the input signal that grating must be detuned. The fibers 26,32,126,158 are also connected to one or more N.times.1 couplers 66,98 to combine input signals from to different input couplers. The switch allows any combination of input wavelengths from any input signal to be selectively switched to one or more output ports.

摘要： A method for phase biasing a fiber-optic SAGNAC rotation sensor is disclosed comprising the inclusion near one end of the sensing coil of a phase modulator consisting of a second coil of fiber free to rotate independently of the sensing coil. The modulator coil is made to oscillate and the desired phase difference modulation is produced by means of the SAGNAC effect in the oscillating coil. Two novel modulator drivers are disclosed. Both have a rigid support hub having radially extending spokes which bend in mechanical synchronism in response to a piezoelectrically induced motive force. The optical fiber is wrapped like a rim around the outside of the spokes for being rotated in an oscillatory manner to effect the desired phase difference modulation.
