摘要：
We present a two-slit time-resolved Young's interference experiment. We use a streak camera, with 2 ps resolution, to measure the arrival time as well as the location of the photons into the detector from an infrared femtosecond pulsed laser. The interfering photons can have the same or different energies as selected from a monochromator. We show that the interference fringes tilt in x-t space and disappear as the difference in energy and the resolution time set in the streak camera increase. The results show deviations from classical interference formulae and a possible interpretation in terms of decoherence may be adequate.
