A diffraction grating based on polyaniline fibers was used to study the effects that occur during the oblique incidence of light rays. Diffractograms of conical diffraction were experimentally obtained for an optical system containing a diffraction grating and a laser. The set of experimental data was approximated using the least squares method. The coefficients of the second-order curves were calculated and the spatial position of the diffraction grating was determined.

Key words: conical diffraction, diffractogram, optical system.
