Abstract:
An electro-optic probe comprising:a laser diode for generating a laser beam based on a control signal from an oscilloscope; a collimator lens for making said laser beam into a parallel beam; a probe body having a probe head rotatably mounted thereto at one end of said body; an electro-optic element affixed to said probe head and rotatable therewith and 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 said collimator lens and said electro-optic element, which passes a laser beam generated by said laser diode and isolates a reflected beam which is reflected by said reflective coating; and photodiodes which convert the reflected beam isolated by said isolator into electrical signals.
