Talk:Common-path interferometer

Common path or common-path? Most referenced works call it "common-path", as does for example the famous "Optical Shop Testing Book" http://rohr.aiax.de/optical-shop-testing.pdf --Frozenport (talk) 08:03, 23 January 2016 (UTC)
Are all of these common-path?
Hi folks, I'm looking at this list and a lot of what I see here wouldn't strictly be called common-path, perhaps a better name for the content held inside this article might be "on-axis". In particular, I'm looking at shearing interference (DIC) which is a technique where contrast is gathered by two beams of opposite polarization. If they travel a common path, you wouldn't see nothin.--Frozenport (talk) 08:21, 23 January 2016 (UTC)
