Abstract
The present invention relates to an electro-optic probe, which includes the following components: a laser diode for emitting a modulating laser light according to control signals generated in a main body of the electro-optic sampling oscilloscope; a first lens for converting the modulating laser light to a parallel beam; a second lens for focusing the parallel beam; an opto-electronic element having a reflection film at a reflection-end; an isolator device disposed between the first lens and the second lens for transmitting the modulating laser light and separating a reflected beam produced at the reflection film into signal beams; and photo-diodes for converting optical energies of the signal beams separated by the isolator device into respective electrical signals; wherein, the signal beams to enter the photo-diodes are directed to propagate towards the laser diode, and the photo-diodes are disposed in a longitudinal direction of a probe casing.
