We present a design for a switchable phase shifter that can be incorporated in a Michelson interferometer. This arrangement uses a pair of ferroelectric liquid-crystal devices with nominal retardations of a quarter wave and a switching angle of 45 deg. It produces phase shifts of 0 and ±90 deg that are almost independent of the wavelength over the range of visible wavelengths.
