Abstract:
An electrooptic probe comprising:an optical path formed within a probe body between a base end portion and a tip end portion of said probe body; a laser diode disposed at an end of said optical path on the base end portion side of said probe body; an electrooptic element disposed at an other end of said optical path on the tip end portion side of said probe body and retained in a probe head constituting the tip end portion of said probe body; a metallic pin provided in said probe head with a base end thereof connected to said electrooptic element, and a tip end thereof protruding from said probe head, wherein a laser beam emitted from said laser diode is incident on said electrooptic element via said optical path, and this incident beam is reflected by a reflecting film provided on said electrooptic element, and the reflected beam thereof is separated and converted into an electrical signal by a photodiode; and wherein said probe head includes a head body for retaining said electrooptic element, and a tip member detachably provided on said head body for retaining said metallic pin; and wherein said electrooptic element and the base end of said metallic pin are connected to each other through a buffer plate for absorbing shock due to contact between said electrooptic element and said metallic pin.
