Abstract

We generated an ultracold Ne atomic beam in the ls3 (J = 0) metastable state by optical pumping of the ls5 atoms stored in a magneto-optical trap. The atomic beam was then diffracted by a computer-generated binary hologram encoded on a SiN membrane. The binary pattern of the hologram was basically the combination of the Fourier tranform of the object pattern and spherical lenses. It reconstructed the object pattern of atoms at a finite distance. The unit size of the hologram was between 200 and 500 nm, and the hologram was composed by 1024 × 1024 units. We could obtain the resolution of 60 micron meter, and the resolving power of 150.
