'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 circular dichroic absorbance of a material i.e. the index of the degree of circular dichroism exhibited, may be defined as the difference between the absorbance of the material for left-handed circularly polarised radiation and for right-handed circularly polarised radiation.
