Abstract
Nematic liquid crystal is used in a transparent patterned electrode ce ll to implement an electrically switchable Gabor lens. The binary Gabo r zone plate used produces only a single pair of conjugate foci, unlik e the multiple foci associated with Fresnel zone plates. Fabrication o f a device is detailed and its focusing ability demonstrated.
