We demonstrate the optical measurements of vibration, inclination, torsion, wind pressure and speed based on a micro abrupt-tapered Mach-Zehnder interferometer. This interferometer has two abrupt tapers in the Er/Yb codoped fiber and thus fractional amount of core mode is converted into cladding modes at the first abrupt taper. The core and cladding modes propagate through different optical paths and meet again at the second abrupt taper to produce interferences for aerospace sensing applications.
