Abstract
An electro-optic probe having a laser diode for generating a laser beam based on a control signal from an oscilloscope body; a collimator lens for making the laser beam into a parallel beam; an electro-optic element having on an end face thereof a reflective coating, with optical characteristics which are changed by propagating an electrical field via a metal pin provided at the end face on the reflective coating side; an isolator provided between the collimator lens and the electro-optic element, which passes a laser beam generated by the laser diode and isolates a reflected beam which is reflected by the reflective coating; and photodiodes which convert the reflected beam isolated by the isolator into electrical signals. The electro-optic element is integrally affixed to a probe head which is rotatable with respect to a probe body on which the probe head is mounted.
