Interrogation of fibre-optic interferometric sensors using an acousto-optic tunable filter
A new technique for the interrogation of interferometric-based fibre-optic sensors using an acousto-optic tunable filter (AOTF) is demonstrated. The scheme involves frequency shift keying (FSK) of the RF drive to the AOTF to track the 3hift of a single fringe peak from an interferometric sensor. Exp...
