Abstract

Imaging ultracold atomic gases close to surfaces is an important tool for the detailed analysis of experiments carried out using atom chips. We describe the critical factors that need be considered, especially when the imaging beam is purposely reflected from the surface. In particular we present methods to measure the atom-surface distance, which is a prerequisite for magnetic field imaging and studies of atom surface-interactions.

    • It took a little googling. Here's a potential answer. The paper the article is based on talks about "absorption imaging". Googling that I found another paper [1] in ArXiV which describes the method a little bit: "absorption imaging, where the attenuation of a laser beam passing…
