Abstract
Отримано дифрактограми розвернутої ґратки, яка складається з волокон полiанiлiну. Проведено аналіз оцифрованих дифракційних картин та апроксимовано методом найменших квадратів набір експериментальних даних. Розраховано кут повороту дифракційної ґратки на основі коефіцієнтів кривих другого порядку.
Diffractograms of rotated polyaniline fiber grating were studied experimentally. Based on the obtained results, the diffraction patterns were analyzed and set of experimental data obtained after image digitization was approximated by the least squares method. The angle of rotation of the diffraction grating was calculated using the determined coefficients of the second-order curves.
