Title: Multiple wavelength optical sources
Inventor: PEZESHKI BARDIA
IPC: H01S3/08
Filed: 2000-10-25
Granted: 2004-12-07
Abstract: Optical pumping arrangements are provided for the broadband or multiple wavelength pumping of optical sources. Sources may be based on Raman gain media and may use multiple output couplers to couple out different wavelength ranges. Configurations may also be used. Overlapping resonators cascaded Ruman resonators at different wavelengths may be configured to share gain media, and may have separate portions in separate optical paths.  Attenuation filters may also be used that are matched to the gain profile of a gain medium, to flatten the gain spectrum and allow equalization of gain to different output wavelengths. In one embodiment, polarization maintaining fiber is used to develop resonant conditions at different wavelengths in different polarization states. Wideband output gratings may be substituted for narrowband gratings to provide CRR configurations with a broader output hand. Broadband amplification may also be provided by using a laser source operating in coherence collapse. The multiple wavelength pumping lends itself to a pumping arrangement in which sources at different wavelengths are combined into separate transmission/gain media such as the different fibers of an optical fiber cable.

Granted: 2009-05-19
Abstract: An optical spectrum analyzer comprises a diffraction grating (DG), a polarization decomposing unit (PDM) for decomposing the input light beam into first and second light beams having mutually-perpendicular linear states of polarization, and two output ports (FP2/1, FP2/2) each for receiving from the grating, substantially exclusively, a respective one of the polarized light beams (LT, LR) after diffraction by the diffraction grating (DG). Each of the linearly-polarized light beams is directed onto the diffraction grating with its linear state of polarization at any prescribed angle to a corresponding plane of diffraction of the diffraction grating. The arrangement is such that the state of polarization of the light beams, at any particular wavelength within an operating band of the analyzer remains substantially unchanged with respect to time. The analyzer also may have a reflector (RAM) for reflecting the light beams leaving the diffraction grating after diffraction a first time so as to return them to the diffraction grating for diffraction a second time.

Patent CA-2455304-C (CA)
Inventor: JOHANSEN ESPEN S
IPC: E21B47/00
Filed: 2004-01-16
Granted: 2008-04-08
Abstract: A method and system for monitoring the operation of downhole equipment, such as electrical submersible pumps, is disclosed. The method and system rely on the use of coiled fiber optic sensors, such as hydrophones, accelerometers, and/or flow meters. These sensors are either coupled to or placed in proximity to the equipment being monitored. As the sensor is perturbed by acoustic pressure disturbances emitted from the equipment, the length of the sensing coil changes, enabling the creation of a pressure versus time signal. This signal is converted into a frequency spectrum indicative of the acoustics emissions of the equipment, which can then be manually or automatedly monitored to see if the equipment is functioning normally or abnormally, and which allows the operator to take necessary corrective actions.

Abstract: Methods and systems for three-dimensionally imaging an apical dome located at the cotyledon end of a plant embryo are provided. Three-dimensional information of an apical dome can be obtained by scanning the apical dome at varying focal planes along an axis of the embryo, or by using multiple cameras arranged in a confocal manner to image the apical dome. It can also be obtained by irradiating the apical dome with polychromatic light, wherein light beams of multiple wavelengths are focused at multiple focal planes along the axis of the embryo so that the dome's height information can be obtained based on the wavelength of the light precisely focused and reflected at each surface paint of the dome. The three-dimensional information is used to ascertain various morphological features (e.g., size, shape, texture, etc.) of the apical dome, which are in turn used to assess the embryo's germinant vigor.

Abstract: A pressure sensor includes an optical waveguide having an optical fiber with a refractive index n1, located in a fiber guide with a refractive index n3, forming an intermediate region. A medium with a refractive index n2 is located in the intermediate region. The refractive indices correspond to the relation n3 > n1 > n2. When subjected to a pressure, the fiber guide is pressed against the optical fiber such that the condition for the total reflection required for the normal optical waveguidance in the optical waveguide is no longer fulfilled, and attenuation takes place. The attenuation is evaluated in a corresponding control unit. The pressure sensor is especially provided for an anti-pinch device in the motor vehicle industry.
