The Fourier slice theorem for range data reconstruction

摘要

This paper proposes a new approach to resolve the ambiguity problem in multistriping laser triangulation systems [1]. The application of this new method to circularly symmetrical objects can achieve time and space complexity of order one. No optical shutter is required in this new method.The new solution is based on the Fourier slice theorem, which forms the basis of X-ray CT (computed tomography) reconstruction. This paper demonstrates how this theorem can also be used to resolve multistripe laser ambiguity effectively.
