Title:
E-O PROBE
Document Type and Number:
Japanese Patent JPH0798329
Kind Code:
A
Abstract:
PURPOSE: To provide an E-O probe capable of measuring through enlarging the voltage distribution in a small region.
CONSTITUTION: A ground transparent electrode 2 and an electro-optical member 3 are fixed in sequence beneath a base 1. A plurality of conical conducting members (electric needles) 5 are fixed to the lower face of a reflecting film 4, and their lower ends are protruded downward. The interval between a plurality of linear electric needles 5 is made narrower toward a measured object arranged below, and the voltage in the small region of the measured object can be enlarged and guided to the electro-optical member 3.
