Optical E-field sensors perform signal measurement including accurate measurement of electric field intensity distribution and broadband frequency, which were not possible under conventional methods. This is because these sensors are based on the measurement principle of an independent Pockels effect and do not use metal coaxial cable.
In addition to applications mostly in research and product development, optical E-field sensors are used for identifying and resolving the causes of EMC problems.

Characteristics
・Causes no interference with metal objects in the surroundings.
・Broadband measurement is possible.
・Measurement information volume is plentiful.
(Frequency, strength, and phase information data can be acquired)
