摘要:

无扩散串扰距离是原子蒸气池中自旋像的一个重要参数,也被认为是空间分辨率的限制。然而,通过对抽运光进行空间和时间调制,利用数字调制器获得了可分辨条纹宽度为13.7~ $μ$ m的汽室自旋像,这比相应的无扩散串扰距离$\sim$ 138~ $μ$ m小得多。分析了扩散和不确定原理对空间分辨率的基本限制。

英文摘要:

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~$μ$m, which is much smaller than the corresponding diffusion crosstalk free distance of $\sim$138~$μ$m. The fundamental limit on the spatial resolution as determined by diffusion and the uncertainty principle is analyzed.
