  1. Introducing QPS Updated Jan 28th 2016 Peter Kung

  2. Objectives Introduce QPS and Peter Kung Review Fiber Grating technology Platform Technologies at QPS Where we can work together Sensor development testing and applications Explore other possibilities

  3. QPS Photronics and Peter Kung Q Quality: means Total customer satisfaction P Performance: How well did we solve the problem , are we the best ? S Service: let customers enjoy working with us

  4. Company Expertise Invented The phase mask Technology enabling volume manufacturing of FBGs Focus on Fiber gratings technology , product and process development with emphasis on automation Work with partners to solve difficult problems in applications in hostile environment Interests in the power industry , Generation , distribution and transmission. Oil and gas exploration and refineries

  5. What is a Fiber Bragg Grating? Fiber L Core Period, Λ Fiber Bragg Gratings Ir Measurand Induced Shift It Ii Transmitted Signal Reflected Signal λ λ λb λb λ

  6. Phase masks , tooling to print fiber Bragg gratings

  7. Phase Mask technology

  8. Benefits FBG is small in size and light in weight Long operating life, immune to radiation Ideal for remote and distributed sensing FBG sensor is passive, draws 0 power Immune to RFI and EMI Can work in hostile environment, like extreme temperature

  9. Twin gratings Cavity

  10. FBG Cavity Reflection Spectrum showing all the fringes

  11. Packaged to protect against dust oil and humidity, improved sensitivity

  12. Packaged SEW vibration sensor

  13. VibroFibre™ Installed on Generator Radial Sensor capsule glued to end winding cap

  14. VibroFibre™ Installed on Generator Tangential Sensor capsule glued to side of end winding cap

  15. Top view of the designed Partial Discharge (PD) sensor Stress relief Optic fiber

  16. Dimensions are in mms connectors will come out of both sides and the length will be shorter

  17. PD Emulator

  18. Working principle of the proximity & non-contact vibration sensor Measured air gap distance Test target FBG air-gap sensor or noncontact Vibration Working distance

  19. Measures small displacement as fringe movements with micron resolutions

  20. Mounted on an optical platform

  21. Measures broad range of vibration non contact (both high and low frequency)

  22. Low frequency vibration (0.1Hz) 时域 Applied detected 输出电压 时间

  23. Please contact Peter Kung to discuss your idea of collaboration Telephone 1-514-697-4728 Cell phone 1-514-578-6766 Email peter@qpscom.com SKYPE: peter.kung.qps Thank you for your time vibration measurement with fiber gratings 23
