'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 common types of polarizers are linear polarizers and circular polarizers. Polarizers are used in many optical techniques and instruments, and polarizing filters find applications in photography and liquid crystal display technology.
