Abstract

Methods, systems and devices for diffractive waveplate lens and mirror systems allowing electronically focusing light at different focal planes. The system can be incorporated into a variety of optical schemes for providing electrical control of transmission. In another embodiment, the system comprises diffractive waveplate of different functionality to provide a system for controlling not only focusing but other propagation properties of light including direction, phase profile, and intensity distribution.
