Abstract
An optical magnification system comprises two Pancharatnam lenses, and provides a first magnification for left-hand circularly polarized light and a second magnification different from the first magnification for right-hand circularly polarized light. An optical magnification system comprises two lenses, each having different focal lengths for left-handed and right-handed circularly polarized light, respectively, and configured to provide a first magnification for left-handed circularly polarized light and a second magnification different from the first magnification for right-handed circularly polarized light.
