The quantitative formulation of Bohr's complementarity in two-path interferometry was investigated. The closely related concept of duality in interferometric devices and the Bohr's complementarity principle are fundamental aspects of quantum mechanics. As in the case of the neutral-kaon system, and Mott scattering of identical nuclei, the study included a variety of conventional double-slit experiments and also particle oscillations. The results show that a unified description can be achieved including a new parameter v, which quantifies the number of fringes one can observe in each specific interferometric setup.
