Ariane Haase coauthored a magnetostriction measurement system using Fibre Bragg gratings as optical strain gauges. The apparatus measured small samples in pulsed magnetic fields, resolving strain of order with a -kHz bandwidth at low temperatures.[ref]
High resolution magnetostriction measurements in pulsed magnetic fields using Fibre Bragg Gratings by Ramzy Daou and others. Author list and abstract, corresponding to Review of Scientific Instruments 81 (2010), 033909: fibre gauges, strain resolution and bandwidth.
