A spectrometer-polarimeter is described for the measurement of the wavelength-dependent general birefringence of single-mode optical fibers and fiber-optic devices. The polarizer rotates, the analyzer is stepped, and a Fourier transform yields the principal axes and retardation. The Poincaré representation of polarization is used throughout.
