Abstract

Angular measurements in symmetrical and nonsymmetrical Fourier spectra are compared. The coefficient of angular magnification of a spectrum and the effective angular extent of a scanning wedge filter are introduced. Better accuracy of angular spectral analysis with an anamorphic Fourier transformer is explained and experimentally proved.
