FAZ and Fugro to present at the “Measuring by Light” Conference on 19th Nov 2015

On the 19th November Fugro and FAZ will give the following presentations at the 2nd bi-yearly edition of “Measuring by Light” 2015 conference

  • FBG based photonic sensing: What is possible? – Johannes Singer (CEO – FAZ Technology )
  • Measuring Sound and Vibration with Light: High-Accuracy Fiber Optic Sensor Solutions – Devrez Karabacak (Principal Technical Advisor – FAZ Technology)


The conference is a two day international event on optical measurement techniques, which will take place on 18 – 19 November 2015 in Rijswijk and Delft. The event is in co-operation with the Vrije Universiteit Brussel, Polytec GmbH, Polytec Benelux, TNO and Shell.

The conference aim is to provide a platform, where both industry and academics can discuss novel measurement techniques and solutions, bridging needs and requirements for both.

October 30, 2015, FBGS announced that they have entered into a strategic partnership with FAZ Technology, Ltd., a subsidiary of Fugro NV, the premium manufacturer of ultra-high resolution measurement devices for Fiber Bragg Grating (FBG) sensors.  Within the partnership, FBGS has the exclusive rights to commercialize the FAZT interrogator platform to the medical market worldwide.

The FAZT Interrogators can be considered as a revolutionary new breed of interrogators for FBG sensors.  Developed for a leading end-user of optical sensors, it is the first sensor interrogator based on a proven telecom tunable laser platform, which delivers unprecedented precision and accuracy.  The integrated electronics and embedded software allow the user to quickly adapt the performance parameters to fit many different sensor configurations.  High-speed data acquisition and an on-board data processing enable straightforward real-time measurements with an extremely high wavelength precision (down to 0.1pm @1kHz).

The partnership will reinforce FBGS’ foothold in the medical market.  Eric Lindner, CEO of FBGS states “Aligning with FAZ Technology gives our customers a unique access to a cutting edge technology that perfectly complements our existing interrogator portfolio and opens new opportunities in the medical market for the current and next generation of FBG sensors.”

The access to this high-end interrogator platform will allow FBGS to launch next-generation turn-key fiber optic sensing solutions based on FBGS’ new fiber developments for “strain-independent temperature monitoring”, “high-resolution localized shape sensing”, and “3D force sensing”.

The partnership is also strongly supported by FAZ Technology.  “We are excited to develop the medical market through FBGS. Due to their unique product portfolio and strong market knowledge, FBGS is in excellent position to develop this market for us. The combination of both of our complimentary products will also bring new sensing capabilities forward to the medical industry and beyond.” says Johannes Singer, CEO of FAZ Technology.

FAZ Technology and FBGS demonstrate advanced capability sensor

At OFS ’24 – The international conference on Optical Fibers held in Brazil,  FAZ Technology and FBGS demonstrated sensors with an enhanced capability to separate strain and temperature measurements. Fibre Bragg Gratings (FBGs) are used in various industries and interest in the technology is still growing. However, the cross sensitivity between strain and temperature can, in certain applications require the need for a temperature compensation FBG to be associated with the strain FBG. An alternative approach is to use FBGs written in birefringent or Polarization Maintaining (PM) fibre. These PM-FBGs (or Bi-FBGs) have a double Bragg peak that allows the simultaneous measurement of strain and temperature but this is often at the expense of the measurement accuracy. At OFS 24 FBGS and FAZ Technology demonstrated enhanced capability of an order of magnitude improvement over existing solutions when using these sensors. The full paper published at OFS ’24 is available here and a video of the demonstration is published here.

Fiber vs Electronic Sensors

Sensors that use electronics use voltage (millivolt, microvolt, nanovolt) and Analogue to Digital (ADC) conversion to convert the voltage to a digital value. Sensors that contain Fiber Bragg gratings use the wavelength of the reflected light measured in nanometers, picometers and femtometers and the equivalent of the ADC is an optical interrogator which translate the wavelength in a digital value. When designing/using electronic sensors the key parameter of sensitivity is specified as volts per minimum resolution of the measurement e.g 100 millivolt (mV) per Pascal for a pressure sensor or 30mV per gravity (30mV/g) , or 1mV per degree Celsius (1mv/°C)

Fibre Bragg gratings use a change in the wavelength of the light reflected from the FBG (Fibre Bragg Grating). The optical interrogator must resolve the wavelength change to a high resolution in order to translate the measurement into a digital value. So the important parameters of sensitivity of a sensor is picometer change in wavelength with respect to the parameter to be measured. e.g. 10 picometer (pm) per degree Celsius (10pm/C), for pressure the typical figure might be 30picometer per pascal (30 pm/Pa), and for an accelerometer it would be 30pm per gravity (30pm/g). (see S.I units documentation for lists of possible standard measurement parameters )

A second parameter of interest is the sample rate of the system. In the case of instrument electronic sensors ADC are usually obtained with a sample rate of from ‘DC’ to 100ksps (100 kilo samples per second) with effective resolutions from 8bit to 20bits. The FAZ optical interrogators are designed for sample rates from ‘DC’ to 44Khz and an effective resolution of up to 20bits (120dB).

The noise floor of an electronic circuit is also an important parameter and us usually represented by volt/√Hz, the equivalent parameter for an optical interrogator is fm/√Hz which can be calculated by taking the square root of the sample frequency (1Khz) and dividing it into the resolution (e.g for a 3Khz 10nm scanning range the I4 noise floor is 18fm the noise per root Hz would then be  18fm /√3000 = 0.33 fm/√Hz). Using these calculations enable us to compare electronic and optical sensors. In seismic applications the FAZ solution matches the performance of electronic sensors with the added benefits of:

  • Do not require any power to be supplied to the sensor
  • Immune to electromagnetic interference
  • Ability to transfer measurement signals over long distances (~10 km)
  • Multiplexing of sensors to enable large sensors counts
  • Suitable for more extreme environments than electronic sensors
