Hi Here (https://www.physicsforums.com/showthread.php?t=119847) it is mentioned that the intensity when passing elliptically polarized light through a linear polarizer will vary when turning the polarizer. Doesn't this only hold assuming the two components of the light are not equal? I mean, the elliptical light could consist of two equal, orthogonal components with a phase of e.g. 20 degrees, but since the amplitudes of the two orthogonal directions are equal, the output intensity shouldn't vary. Best, Niles.
