What is the phase difference between the right circularly polarized and left circularly polarized light of the same amplitude? And how do you calculate it?
mfb said:That depends on your light source and your coordinate system.
Your question is similar to "how to calculate the length of a road?" without any additional information.
Phase shift refers to the delay in the oscillation of a wave, while circular polarization refers to the orientation of the wave's electric field. Phase shift can occur in waves of any polarization, while circular polarization only occurs in waves with a specific orientation of the electric field.
Phase shift is measured in degrees or radians, and can be calculated by comparing the starting point of a wave to its current position. It can also be measured using specialized equipment such as an oscilloscope.
Phase shift can be caused by a variety of factors, including changes in the medium through which the wave is traveling, reflections, and interference with other waves. It can also be intentionally introduced through the use of phase shifters.
Circular polarization is created by combining two waves of equal amplitude and perpendicular polarization that are out of phase by one quarter of a wavelength. This results in a rotating electric field that traces out a circle as the wave propagates.
Phase shift and circular polarization have a wide range of applications in fields such as telecommunications, radar, and optics. They are used to control and manipulate waves for various purposes, such as signal processing, data transmission, and imaging.
