Application of Grey Relational Analysis to Influential Factors on the Optical Fiber Sensor Measurement of the Strain

摘要

In the present study, the Mach-Zehnder interferometric technique is applied to performing sixteen experimental runs on both the three- and four- point bending tests, as well as five runs on the uniaxial tension test, to determine the most impacting factor. The average strain attained from the optical intensity by the aforementioned techniqued is selected as the quality target. By analyzing the gey relational grade matrix, the factor that is the most influential can be picked. Of all candidates under consideration, the length of the optical fiber is found to be the most dominant and sensitive associated with the accuracy of all three experimenta measurements.
