Abstract
Apparatus and method for mapping an existing electric field involve exposing a field responsive element to the electric field to produce movement of the element in the path of a light beam, and detecting modulation of the light beam by the element. In a preferred embodiment the light beam is passed to and from the field responsive element by optical waveguides.
