“…In contrast, Bragg gratings in multimode fibres (MMFs) receive much less attention. Some publications have reported recently conceptual studies of multimode FBG (MMFBG) based sensor applications [13][14][15][16][17][18][19][20][21].…”

We present a fibre optic sensing system for simultaneous strain and temperature measurement based on a narrow band variable optical reflector. The variable optical reflector comprises a single mode fibre Bragg grating and a fibre mode converter. A 2 µm m−1 strain resolution is achievable over a range of 2000 µm m−1 with a temperature accuracy of 0.3 °C. A strain sensor with a range of 12 000 µm m−1 is also demonstrated. The sensing system shows high strain and temperature sensitivities with very good stability.
