       | IIUC, the article seems to define the term "light phase" to mean
       | what a layman light me would call "brightness". But it seems
       | crazy to me that they'd overload the term "phase", when it has a
       | very obvious alternative definition in the field of optics.
       | 
       | Can someone clarify if that's what the article is actually
       | saying?

         | visualize phase shifts by transforming phase shift gradients

         | To detect phase changes you have to turn them into amplitude

         | amplitude-change a "phase change." Yes, this elides a critical
         | part of the interpretation, but if we were to insist on
         | carrying around a complete interpretation with every noun we'd
         | wind up with nouns as long as textbooks. Even Germans don't
         | take it that far.
