Abstract:
An electro-optic probe comprises:a laser diode for emitting a laser beam based on control signals of an oscilloscope body; a first lens for collimating the laser beam into a parallel beam; a second lens for condensing said parallel beam; an electro-optic element having a reflecting film on one end surface; an isolator for isolating the reflected laser beam reflected by said reflecting film after the laser beam emitted by said laser diode passes to the reflecting film; and a plurality of photodiodes for converting the reflected laser beam into the electric signals after being separated by said isolator; wherein, optical components constituting said isolators are disposed inclining to the optical axis at an angle such that the light beams reflected on surfaces of said optical components by regular reflection do not enter said photodiodes.
