Abstract ： With the help of the perturbation method and the Feynman path integral technique, we analytically demonstrate that, when the electronic spectrum of a mesoscopic box is measured through two connecting leads, there exists a class of new diffraction phenomena in the coherence time domain, based on the new coherent tunneling model. It is shown that the new diffraction effect determines the minimal resolvable coherence time to the Heisenberg limit. In particular, Fraunhofer optical phenomena, such as missing order and grating effects, can be reproduced in the meso-systems. The predicted periodic oscillations as a function of voltage are in excellent agreement with experimental observations.
