摘要：A voltage detector detects a voltage developing in a selected area of an objectsuch as an integrated circuit by utilizing an electro-optic material equipped in an opticalprobe. A change in refractive index of the electro-optic material which is caused by thevoltage in the object, is detected as a change of polarization of a light beam passingthrough the electro-optic material. In order to improve the detection sensitivity thevoltage detector is equipped with an optical means for making light paths of an inputlight and an output light different from each other.
