• The diffusion crosstalk free distance is an important parameter for spin images in atomic vapor cells and is also regarded as a limit on the spatial resolution. However, by modulating the pumping light both spatially and temporally using a digital micromirror device, a spin image of a vapor cell has been obtained with a distinguishable stripe width of 13.7  μm, which is much smaller than the corresponding diffusion crosstalk free distance of ∼138  μm. The fundamental limit on the spatial resolution as determined by diffusion and the uncertainty principle is analyzed.
