The reason you see those is that the air has different densities at different temps, and the light bends slightly as it passes from one density to another.
I wonder if you can use a laser to help confirm a cold spot in that manner...hmm.
my guess is that the level of accuracy needed to detect changes like we need, which seem relatively small to effect a light source, might be pretty expensive.
Exactly... We do not need anything supper accurate. Just basic layout of the facility and surrounding buildings in which we will be investigating. I would imagine that each floor will be the same, so what in addition to the floors do we need to keep in mind?
