Cholesterics
WebThe orbital angular momentum of light represents a fundamentally new optical degree of freedom. Unlike linear momentum, or spin angular momentum, which is associated with the polarization of light, orbital angular momentum arises as a subtler and more complex consequence of the spatial distribution of the intensity and phase of an optical field - … WebThe Liquid Crystals are the only holistic representations of the mineral kingdom and most potent form of crystalline energy on earth.
