Abstract

A cantilever optical vibrometer using a fiber Bragg grating (FBG) is developed. The sensor head Is made by attaching an FBG to a triangular beam to provide position-independent strain for the purpose of acceleration measurement. The vibrometer demonstrates a noise-limited acceleration resolution of 2.8×10-4g/√Hz with repeatability error of less than 2.4%.
