ABSTRACT The ratiometric wavelength-measurement system is modeled and an optimal design of transmission response of the employed edge filter is demonstrated in the context of a limited signal-to-noise ratio of the signal source. The corresponding experimental investigation is presented. The impact of the limited signal-to-noise ratio of the signal source on determining the optimal transmission response of edge filters for a wavelength-measurement application is shown theoretically and experimentally.

    ABSTRACT: As a contribution towards the development of all-fiber technology, in this paper we present two all- fiber systems based on macro-bend loss in single-mode fiber, an FBG interrogation system and a temperature sensor, both of which use a common ratiometric power measurement scheme. An interrogation system based on a macro-bend fiber filter has a wide measurement range and a capability to interrogate multiple FBG sensors when used together with a tunable filter. The optimization of the interrogation system is discussed, taking account of the polarization and temperature dependency of the fiber filter and noise of the system. A temperature sensor using a macro-bend fiber filter which has a linear relationship between the bend loss of the singlemode fiber and temperature is also presented for the first time. By measuring the change in ratio of the system, a change in temperature can be measured assuming the system is calibrated.

    ABSTRACT: Analysis and performance evaluation of a macro-bend fiber based interrogation system for a Bragg grating sensor array is presented. Due to the characteristic properties of the macro-bend fiber filter such as polarization and temperature dependence and the total noise associated with the ratiometric system, a best fit ratio slope is required to interrogate multiple fiber Bragg gratings (FBGs) whose peak wavelengths are spread over a wide wavelength range, rather than the optimal slope for individual FBGs. In this study, we have used an FBG array with 5 FBGs with peak reflected wavelengths lying between 1525 and 1575 nm. The analysis of the system is carried out and a fiber filter with a slope which covers a wavelength range of 1525–1575 nm is selected which ensures a resolution and accuracy for all the FBG sensors in the array as close as possible to that which would be achieved with a filter with an optimal slope for each FBG. Performance evaluation of the system is carried out and the static strain, dynamic strain, and temperature are measured with the developed interrogation system.

    ABSTRACT: A method for reference strain measurement for FBG strain sensor in the testing stage while applying strain using actuators like piezo translators or micro screw is introduced. Unlike conventional methods of surface mounting, in our method the strain gauge is affixed directly to the optical fibre, which allows it to use with systems where the strain is applied directly using actuators while testing the FBG sensing system. Different bonding techniques were tested and a comparison with the results from calculated values are presented. Since the contact area between the fibre and strain gauge is very small, a corrected gauge factor is calculated and is used to measure the strain transfer. As a demonstration of the developed method, the strain gauge is used as a reference in an edge filter based FBG sensors interrogation system, where the strain was applied using a micro screw. The measured strain using foil strain gauge affixed to the optical fibre and FBG sensor interrogation system are in close agreement. © 2007 Wiley Periodicals, Inc.
