Question

What is polarization ratio?

Answer 1

1. Polarization is a property applying to transverse waves that specify the geometrical orientation of the oscillations.
2. The degree of linear polarization is quantified with the polarization extinction ratio.
3. The ratio of optical powers in the two polarization directions is called polarization ratio.
4. The ratio uses the unit of decibel (dB).
5. It is used as a proxy for measuring the degree of polarization of a depolarizer or low polarization light source.
6. The polarization extinction ratio will be close to zero, because the light is evenly distributed over all polarizations.
