Care must be taken, as in Stokes's analyzer, to insure that R' and 

 R are complementary to the azimuth of the major axis of the in- 

 cident light, since otherwise the sign of e o will be incorrect. 



By starting with plane polarized light the constants of the an- 

 alyzing system (17) and compensator (AY) can be measured. 

 Since the incident light is plane polarized, e=o and (73) and (74) 

 reduce to:
