摘要
The characteristics of a modal liquid-crystal focusing device are experimentally investigated in different control regimes. Phase delay distributions in the form of a circular truncated cone with a controlled position of the base centre are obtained. Focusing to a round spot with a controlled position of the focal point in the aperture area is implemented for the focusing device operation in the regime of a small modal parameter.
