    Micro-Air-Gap Based Intrinsic Fabry-Perot Interferometric Fiber-Optic Sensor
    Chen, X. P.; Shen, F. B.; Wang, Z. A.; Huang, Z. Y.; Wang, Anbo (Optical Society of America, 2006-05-01)
    A simple intrinsic Fabry-Perot interferometric (IFPI) sensor is developed. The sensor is fabricated by two micro air gaps as reflective mirrors in a fiber to form a Fabry-Perot cavity. Theoretical and experimental studies of the sensor are described. Experimental results show that high resolution and high sensitivity can be achieved. Two structures of micro-air-gap-based IFPI sensors offer more applications than other IFPI sensors. (c) 2006 Optical Society of America.

    Principles And Design Of Multibeam Interference Devices: A Microelectromechanical-Systems Segment-Deformable-Mirror-Based Adaptive Spectrum Attenuator
    Huang, Z. Y.; Zhu, Y. Z.; Wang, Anbo (Optical Society of America, 2005-12-01)
    Fourier analysis of multibeam interference shows that the total electric field and relative time delay of the beams form a Fourier-transform pair. Fourier-analysis-based multibeam interference analysis and device design is discussed in detail. The principle of the proposed segment-deformable-mirror-based adaptive spectrum attenuator is illustrated. (c) 2005 Optical Society of America.

    Self-Compensating Fiber Optic Flow Sensor System And Its Field Applications
    Peng, W.; Pickrell, Gary R.; Huang, Z. Y.; Xu, J. C.; Kim, D. W.; Qi, B.; Wang, Anbo (Optical Society of America, 2004-07-01)
    A self-compensating fiber optic flow sensor system based on the principle of broadband white-light interferometers and cantilever beam bending is described. The fiber optic sensor system uses two fiber ferrule sensors that are bonded on either side of a cantilever beam to measure the flow rate by monitoring the air-gap changes caused by the bending of the cantilever beam. Cross sensitivity of the temperature and pressure dependence of the sensor can be compensated for automatically. The prototype sensor system was constructed, laboratory characterized, and field tested. The results from the field testing have demonstrated high resolution, repeatability, and stability for on-line detection of the flow rates of fluids. (C) 2004 Optical Society of America.
