Glenn,
A polariscope is a device that allows optical stress analysis. The process
is commonly called photoelasticity. It's an old experimental stress analsyis
technique, having been around for decades.
The fringe pattern of an object can be viewed through a polariscope. The
fringes can be used to determine stress magnitudes of a transparent plastic
part in the polariscope. The material fringe value is a measure of how
'optically active' the material is - it tells how many finges you will get
at a certain stress (a few other factors must be considered).
