Schlieren Interferometry
In the next agora session (it will be on Thursday 2nd of December, food will be provided) we start a new subject entitled Schlieren interferometry.
This type of interferometry is interesting to measure temperature and velocity of fluids.
Therefore, I suggest you to start reading the following paper:
Schlieren interferometry. An Optical Methods for determining temperature and velocity distribution in liquids
J.Bruce Brackenridge and W.Paul Gilbert, vol. 4, No. 7, 819, 1965 Applied Optics.
