Abstract: Superimposed phase diffraction gratings were formed by an electron beam in amorphous arsenic sulfide (As₂S₃) films. The number of superimposed gratings was N = 2–10 and the angle of slant was π/N. The electron-beam-stimulated modulation of the refractive index n₁ = 10^-3–10^-2 of the superimposed gratings was studied as a function of the number of these gratings. The main factor which limited the number of mutually independent superimposed gratings was the limit of linearity of the response of the recording medium at the nodal regions where the total radiation dose was maximal.
