Surface Acoustic Wave Fiber Optic Sensor
Surface acoustic wave technology takes advantage of the in its operation. Most modern surface acoustic wave sensors use an input (IDT) to convert an electrical signal into an acoustic wave. The sinusoidal electrical input signal creates alternating polarity between the fingers of the interdigitated transducer. Between two adjacent sets of fingers, polarity of the fingers will be switched (e.g. + - +). A.
