Leak Testing using Photoelasticity

Has anybody ever used photoelasticity for leak testing and is there some literature on this topic?

Johannes, I do not think that photoelasticity would be appropriate. However, Settles describes a schlieren system that he configured in 1997 using a linear fluorescent tube and had a viewing area of 1x3m. Convective heat transfer and gas leaks provide the variation in density required for the schlieren principle to work.
See; Schlieren and Shadowgraph Techniques, by G.S.Settles, Springer Verlag, 2001 (page 107)
