'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.
DETAILS. Snapshot 1: For the very special cases of 90- and 270-degree phase differences with equal and components, you get circularly polarized light. Snapshot 2: If the phase difference is nonzero, then in general you get elliptical polarization.
