Let 𝒫 be an n-dimensional convex polytope and 𝒮 be a hypersurface in ℝ^n. This paper investigates potentials to reconstruct 𝒫 or at least to compute significant properties of 𝒫 if the modulus of the Fourier transform of 𝒫 on 𝒮 with wave length λ, i.e., |∫_𝒫 e^-i1/λ𝐬·𝐱 𝐝𝐱| for 𝐬∈𝒮, is given, λ is sufficiently small and 𝒫 and 𝒮 have some well-defined properties. The main tool is an asymptotic formula for the Fourier transform of 𝒫 with wave length λ when λ→ 0. The theory of X-ray scattering of
