Dynamic-strain measurement with dual-grating fiber sensor
Applied Optics
|February 15, 2008
Abstract:
A dual-grating sensor head, which was designed for temperature-insensitive strain measurement, was used to measure fast-varying strain perturbations. Using a Mach-Zehnder interferometer technique, we obtained ~0.1-muepsilon (microstrain) rms resolution with a 200-Hz strain input. The feasibility of measuring a dynamic-strain with a static-strain measuring configuration was also demonstrated.

01:27Measurements of Strain
Strain quantifies the deformation of a material under force, typically measured as normal strain, which represents the change in length when compared with the original length. Electrical strain gauges are used for enhanced accuracy. These devices consist of a conductive wire mounted on a paper backing that adheres to the material's surface. These gauges operate on the piezoresistive effect, where the wire's electrical resistance changes in response to mechanical deformation. The strain gauge...
01:15Design Example: Strain Gauge Bridge or Wheatstone Bridge
The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...
