## Abstract A quadrature phase‐shifted white‐light interferometry is demonstrated to interrogate short‐cavity extrinsic Fabry–Perot interferometric (EFPI) sensors. The absolute cavity length of an EFPI can be recovered by constructing two quadrature signals using the white‐light spectrum of the EFP
