OCT PROBE USING PZT

摘要

An OCT probe which uses a PZT according to the present invention includes: an external case of a cylindrical shape; a vibration body having a main body, which is finely adjusted in X-axis and Y-axis by forming a part of a hollow hole shape having a predetermined length and formed with a pressing element in a globular shape joint part, and multiple electrodes, which are arranged along the outer circumference surface direction of the main body so that the main body vibrates by supplying a sinusoidal voltage; a base which is arrange in the external case and is combined with the main body by forming a groove of a globular shape which corresponds to the globular shape joint part of the main body in the inner surface; a screw part which combines and fixates the main body on the base by inserting into a penetration hole which is formed in the external case and the base; and an optical fiber which receives light which is reflected or scattered on a subject by radiating light to the subject, is arranged to penetrate the inside of the main body, and has a middle part whose length is fixated by a ferrule which is inserted into an end part of the main body at a predetermined depth. The present invention is able to correct into an accurate circle trace by easily and finely adjusting to an X-axis and a Y-axis by processing a part of the PZT vibration body into a globular joint part when forming the circle trace capable of obtaining an inspection part in a three-dimensional image by the PZT vibration body which vibrates when applying a voltage.
