The author investigates local tomography in the case of limited-angle data. The main theoretical tool is analysis of the singularities of pseudodifferential opertors (PDO) acting on piecewise smooth functions. Amplitudes of the PDO are allowed to be nonsmooth in the dual variable \(\xi\) across the boundary of a wedge. Results of numerical simulation of limited-angle local tomographs confirm basic theoretical conclusions.
