AMAP sensor demonstration. (a) Key dimensions in a section of the optical fiber core in the AMAP sensor; (b) test panel made of an aluminum alloy with the wave generation element, AMAP sensor, and bonded disc, attached to simulate a damage, as a source of reflected waves; (c) spectral decomposition of the AMAP sensor response measured for a selectively excited mode in the absence of the bonded disc (top) and after attachment of the disc (bottom) [20].
