Imaging photoelastic samples

Using polarizers properly:
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
Should I use a circular or a linear polarizer? Should I add a quater-wave plate? How to orient the whole thing and check that I did it properly? [This section]() gives details about all these points.

Transmission photoelasticy:
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
This is a method to image photoelastic material when you have optically access to both sides of the sample. In this case you lit the sample from one side and observe it from the other side. More details about this method are give [here]().

Reflection photoelasticy:
|
|
|
|
------------------------
|
|
|
|
|
|
|
|
This is a method to image photoelastic material when you have optically access to just one side of the sample. In this case you lit the sample from the side you also observe it, the light is reflected on the back of the sample and go trough it two times.More details about this method are give [here]().
