Detonation velocity measurements with uniform fibre Bragg gratings
Abstract:
In this paper we demonstrate a simple and new fibre optic technique for measuring detonation velocities using uniform fibre Bragg gratings. We compare this new system with chirped fibre Bragg grating diagnostics and show how coherent source illumination can yield spatial uncertainties below ±10 μm - a percentage error that is an order of magnitude lower than the broadband ASE methods we have tested.
