New methods for reducing signal distortion in interferometric angular velocity measurements are introduced. Two waveform approaches are proposed: long‐wavelength signals and short‐pulse signals. The source of nonlinear distortion is derived and analysed, and the strengths and drawbacks of each method are discussed. Although the focus is on the distortion generated when measuring the angular velocity of walking humans, the results are applicable to interferometric measurements of the angular velocity of non‐rigid or multiple objects in general.
