  • Fiber-optic Displacement Sensor based on the DBR fiber laser
    Photonic Sensors, 2014
    Co-Authors: Guoyu Li, Kang Yang, Yan Li, Mingsheng Liu
    Abstract:

    The fiber-optic Displacement Sensor based on the distributed Bragg reflector fiber laser is proposed, that is, the fiber laser cavity is attached to the measured object, when the measured object is stretched or contracted, and the length of the fiber laser cavity is changing too. In view of nonlinearity of the fiber-optic Displacement Sensor, the calibration based on piezoelectric ceramics is applied to improve the linearity of the Displacement Sensor. Experiment results show that the fiber-optic Displacement Sensor has a linear response with the nominal working distance of 90 μm. Furthermore, the fiber-optic Displacement Sensor may realize the dynamic measurement. © 2012 SPIE.

    Co-Authors: Guoyu Li, Yan Li, Kang Yang
    Abstract:

    The fiber-optic Displacement Sensor based on the distributed Bragg reflector fiber laser is proposed, that is, the fiber laser cavity is attached to the measured object, when the measured object is stretched or contracted, and the length of the fiber laser cavity is also stretched or contracted accordingly. In view of the nonlinearity of the fiber-optic Displacement Sensor, the calibration based on piezoelectric ceramics is applied to improve the linearity of the Displacement Sensor.

  • Fiber Optic Radial Displacement Sensor-Based a Beam-Through Technique
    IEEE Sensors Journal, 2016
    Co-Authors: Mundzir Abdullah, Mohd Fakaruddin Sidi Ahmad, Ganesan Krishnan, Noriah Bidin, Muhammad Yasin
    Abstract:

    Fiber optics Displacement Sensor based on beam through technique has wide application due its simplicity, high accuracy and immune to electromagnetic interference. The fingerprint for such Sensor system is established via the longitudinal Displacement. However it is known that the highest intensity modulation is normally fall at zero distance for beam through technique. Thus it is valuable to take advantage at such optimization position. A novel method is introduced by conducting a fiber optic Sensor based radial Displacement. Three types of fiber optic including 1000, 500 and 265 ?m core diameters were employed to optimize the probe. Gaussian profile is identified to be the fingerprint for radial Displacement Sensor which entirely different with a linear one for longitudinal Displacement. The radial Displacement fiber optic Sensor is a core diameter dependent. The bandwidth at FWHM tends to be broader with the core diameter of fiber optic. Higher response of the Sensor is achieved at the negative side of the Gaussian curve comparable to positive part. It is realized that the sensitivity of the radial Sensor is 7 times higher correspond to core diameter and 3 times better performance than conventional Displacement Sensor.

The radial Displacement fiber optic Sensor is a core diameter-dependent. The bandwidth at full width half maximum tends to be broader with the core diameter of a fiber optic. Higher response of the Sensor is achieved at the negative side of the Gaussian curve comparable with positive part. It is realized that the sensitivity of the radial Sensor is 7 times higher correspond to core diameter and 3 times better performance than the conventional Displacement Sensor.

  • nano Displacement Sensor based on photonic crystal fiber modal interferometer
    Optics Letters, 2015
    Co-Authors: Jitendra Narayan Dash, Joel Villatoro, Sumit Dass
    Abstract:

    A stable nano-Displacement Sensor based on large mode area photonic crystal fiber (PCF) modal interferometer is presented. The compact setup requires simple splicing of a small piece of PCF with a single mode fiber (SMF). The excitation and recombination of modes is carried out in a single splice. The use of a reflecting target creates an extra cavity that discretizes the interference pattern of the mode interferometer, boosting the Displacement resolution to nanometer level. The proposed modal interferometric based Displacement Sensor is highly stable and shows sensitivity of 32  pm/nm.
