Abstract
A renewable liquid reflection grating. Electrodes are operatively connected to a conducting liquid in an arrangement that produces a reflection grating and driven by a current with a resonance frequency. In another embodiment, the electrodes create the grating by a resonant electrostatic force acting on a dielectric liquid.

A renewable liquid reflection grating, comprising:
- a conducting liquid, and
- electrodes operatively connected to said conducting liquid in an arrangement that produces said reflection grating and driven by a periodic current with a resonance frequency.
A method of producing a liquid reflection grating, comprising
- providing a conducting liquid,
- positioning electrodes relative to said conducting liquid in an arrangement that produces said reflection grating and actuating them by a periodic current with a resonant frequency.
A method of producing a liquid reflection grating, comprising
- providing a dielectric liquid,
