    摘要: A sensor to simultaneously detect light and acoustic waves is presented. The sensor includes one or more optical fibers and a diaphragm disposed near one end of at least one of the one or more optical fibers. The diaphragm is configured to vibrate upon incidence of acoustic waves from an arc flash and reflect a light beam into at least the one of the one or more of the optical fibers. A semi-transparent region is disposed around the one or more optical fibers to diffuse light originating from the arc flash into at least one of the one or more optical fibers.

    摘要: A system (100) for controlling a wind turbine (300) is disclosed. A system (100) includes a light source (110) and a beam scanner (120) to scan the light pulses over the wind turbine (120). The system (100) further receives backscattered light pulses and subsequently, provides a signal corresponding to the light pulses. The system (100) adjusts a threshold of the signal based on a normalized value of a detected peak value of the signal. The system (100) associates a time of flight with each of the received backscattered light pulse. The system (100) generates an image of the wind turbine based on the time of flight associated with the light pulses and subsequently, compares the generated image with at least one known image of the wind turbine. The system (100) generates a health profile of the wind turbine (300) based on the comparison and subsequently, change one or more parameters of the wind turbine (300) based on the health profile.

    摘要: A sensor (100) includes a sensor head (102) including an acoustic detector (106) configured to receive light (114) from a first light source (304) and to reflect the light (118) upon incidence of acoustic waves (116). The sensor also includes at least one optical fiber and (104) at least one fluorescent material within at least one of the sensor head and the at least one optical fiber (104). The at least one fluorescent material is configured to receive light (120) from a second light source (326) external to the sensor and emit visible light (204) in response to the light received from the second light source.

    摘要: A wind anemometer (10) comprises a light source (12) for transmitting pulsed light signals (20), a receiver (14) for receiving backscattered signals (28) from airborne particles for each pulse of the transmitted pulsed light signals (20), a detector (16) for detecting the received backscattered signals, and a processor (18) to determine location of the airborne particles (32) with respect to the anemometer (10) based on the detected backscattered signals (38). The processor estimates wind velocity using changes in location of the airborne particles over at least one time interval.
