  In this paper, we consider the Dirichlet Laplacian operator -{\Delta} on a
curved quantum guide in R 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. keywords: Inverse Problem, Quantum Guide,
