摘要：

The authors demonstrate that in-fibre Bragg gratings may be successfully used to measure megahertz acoustic fields if the grating length is sufficiently short and the optical fibre is appropriately desensitised. A noise-limited pressure resolution of 4.5 x 10(-3) atm/root Hz was found. The capability to simultaneously act as a temperature sensor is also demonstrated.
