We consider the Dirichlet Laplacian operator Δ on a curved quantum guide in 𝑛 ( 𝑛 = 2 , 3 ) with an asymptotically straight reference curve. We give uniqueness results for the inverse problem associated to the reconstruction of the curvature by using either observations of spectral data or a boot-strapping method.
