## Abstract A quadrature phaseโ€shifted whiteโ€light interferometry is demonstrated to interrogate shortโ€cavity extrinsic Fabryโ€“Perot interferometric (EFPI) sensors. The absolute cavity length of an EFPI can be recovered by constructing two quadrature signals using the whiteโ€light spectrum of the EFP
