A Passive All-Dielectric Field Probe For R.F. Measurement Using The Electro-Optic Effect

An electric field sensor capable of measuring alternating fields at frequencies up to 150MHz has been demonstrated. The sensor uses the linear electro-optic effect, allowing the construction of an all dielectric probe. With modifications to the light source and receiver, the sensor should be capable of measuring fields at frequencies up to 1 GHz.
