A study was performed on optical mask for laser-cooled atoms. An optical mask is a standing wave of light in resonance with an open atomic transition. The mask depleted the population of the initial internal state everywhere except in a narrow vicinity of the nodes. It was found that the optical mask was a useful tool for creating a periodic pattern in the density of cold rubidium atoms. The instrumental width of the imaging technique was limited due to an effect of the dipole force rather than the initial velocity spread.
