Hi,
I have a question regarding the projection of polarised light onto a screen, such as commonly used in 3D or VR cinemas. I'm only concerned with linearly polarised light for the moment.
I understand that when light undergoes reflection the polarity is altered.
I've attached a diagram. Light from projector is typically polarised at 45 degrees to the horizontal.
My question is, is the polarity of the reflected light a function of:
Thanks in advance,
M
I have a question regarding the projection of polarised light onto a screen, such as commonly used in 3D or VR cinemas. I'm only concerned with linearly polarised light for the moment.

My question is, is the polarity of the reflected light a function of:
a) angle of incidence θi,
b) the angle of reflectance to the eye θv,
c) or the difference between v and r: θvr, or
d) none of the above?
Is there a simple expression, or does it depend greatly on the optical properties of the screen material? Does the Brewster angle have anything to do with this?b) the angle of reflectance to the eye θv,
c) or the difference between v and r: θvr, or
d) none of the above?
Thanks in advance,
