摘要： A method and device for pressure sensing using an optical fiber having a core, a cladding and a Bragg grating imparted in the core for at least partially reflecting an optical signal at a characteristic wavelength. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a pressure sensitive structure so as to allow the characteristic wavelength to change according to pressure in an environment. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to at least a portion of the diameter of the variation region and a butting mechanism which holds the ferrule against the optical fiber.

摘要： An optical beam homogenizer includes an entrance pupil through which a non-uniform optical beam propagates. A first optical component having plural flat surfaces receives the input beam. The flat surfaces of the first optical component effectively segment the entrance pupil by dividing the input beam into plural beamlets, one beamlet for each pupil segment and flat surface. The beamlets are received by a second optical component which also has multiple flat surfaces, each flat surface receiving a beamlet. The second optical component directs the beamlets toward each other such that they overlap at an exit pupil of the system. The second optical component also focuses the beamlets such that an image of each entrance pupil segment is formed at the exit pupil. The images of the individual entrance pupil segments are superimposed upon each other at the exit pupil to form a uniform optical output beam.

摘要： An optical speed sensor includes a laser diode 10 that provides a broadband source light 12 to a coupler 18 which provides a source light 22 to a fiber Bragg grating 26 which reflects a first reflection wavelength of light 28 and passes the remainder as a light 30. The light 30 is incident on another fiber Bragg grating 32 which reflects a second reflection wavelength of light 34. The power of an output signal 40 is indicative of the reflected light beams 34,28, and is measured by a photodetector 46. The gratings 26,32 are mounted on a magnetostrictive material 60 which is connected to a permanent magnet 62 which is connected to a material 70 which conducts magnetic fields. The material 60 expands and contracts in response to the strength of magnetic fields therein. The reflection wavelengths for both gratings 26,32 are the same when the tooth 100 is not nearby, thereby causing the output signal 40 to be primarily equal to the reflected light 28. However, when the tooth 100 is nearby, the material 60 and the grating 32 expands causing the reflection wavelengths to separate, thereby causing the power of the output signal 40 to increase. Because both gratings 26,32 are on the same material thermal expansions will have no effect on the sensor measurement. Alternatively, one of the gratings 26,32 may be mounted to the material 70 or the magnet 62. The detection may performed in either reflection or transmission mode.

摘要： A signal processor receives a signal containing information about a sensor that is spirally wrapped at a known pitch or separation down a pipe having a flow; and determines a flow velocity based at least partly on the information contained in the signal received by applying an autocorrelation function that depends on a relationship between the time between a repeating pattern and the known pitch or separation of the spirally wrapped sensor. The signal processor provides a corresponding signal containing information about the flow velocity. The sensor includes a strain sensor, including a piezo-electric polymer strain sensor fabricated from PVDF, and/or two or more equally spaced spirally wound sensors. The determining includes correlating output signals of two or more equally spaced spirally wound sensors to determine a time delay, and determining the flow velocity based on the time delay and the known pitch or separation.
