Abstract
A method of interrogating a phase based transducer by providing a pulsed input including two different wavelengths in which the different wavelength components can be used to derive a phase change experienced by a synthetic wavelength, and by arranging for the synthetic wavelength to be significantly greater that the component wavelengths, the phase so detected has a reduced sensitivity, and is less susceptible to overscaling effects.
