'In many ways, the manufacturing strategy is helping us redefine and reinvent how we do business in General Motors,' said Scott Whybrew, GM's executive director of global manufacturing engineering.
When the phase shift is exactly Â±90Â°, then circular polarization is produced (fourth and fifth figures). Thus is circular polarization created in practice, starting with linearly polarized light and employing a quarter-wave plate to introduce such a phase shift.
The complete polarization of monochromatic light is characterized by the projection of the path of the end of the electric vector (Figure 1) at each point of the ray onto a plane perpendicular to the ray. In the most general case of elliptical polarization, the projection is an ellipse.
