Flexural beam-based fiber Bragg grating accelerometers

A flexural beam is utilized as the primary transduction mechanism for demonstrating a series of fiber Bragg grating (FBG) accelerometers. The fully packaged FBG accelerometers reported in this work have many desirable features including good acceleration sensitivity (212.5 μ/spl epsiv//g), high reso...

Description
Summary:A flexural beam is utilized as the primary transduction mechanism for demonstrating a series of fiber Bragg grating (FBG) accelerometers. The fully packaged FBG accelerometers reported in this work have many desirable features including good acceleration sensitivity (212.5 μ/spl epsiv//g), high resonant frequencies (on the order of 1 kHz), very low cross-axis sensitivity (
