    Abstract

    We have demonstrated direct imaging of interference fringes of total atomic density with periods λ/4 and λ/2 for optical wavelength λ that have been produced in a de Broglie wave atom interferometer. The imaging was done by means of an "optical mask" technique, which allowed us to observe subwavelength periodic patterns with a resolution of up to λ/16. In addition, the dependence of the fringe pattern on the recoil phase and pulse area reveals quantum dynamics in the atomic center-of-mass motion. The behavior of the fringe patterns near the interference times distinguishes the effects of phase gratings from those of amplitude gratings.
