Claim Text:
1. A vectorial optical field generator comprising a radiation source, a modulator surface, a first quarter wave plate, a second quarter wave plate, and an output plane, wherein: the radiation source emits an input radiation along a path; the modulator surface is positioned along the path and configured to modulate: the first quarter wave plate is positioned along the path such that the input radiation travels through the first quarter wave plate, reflects off of the second area of the modulator surface, and back through the first quarter wave plate; the second quarter wave plate is positioned along the path such that the input radiation travels through the second quarter wave plate, reflects off of the third area of the modulator surface, and back through the second quarter wave plate; and the output plane is positioned along the path and receives output radiation resulting from modulating the input radiation with the modulator surface, the first quarter wave plate, and the second quarter wave plate.
