  • Patent number: 4682221
    Abstract: This invention relates to a non-contact electro-optical displacement follower which captures the image of a target or device under test optically, converts the said image into an electron image by optical-electrical conversion, and measures displacement. It forms a variable voltage which moves the electron image on the displayer to the desired location and can be applied to each deflection coil (8, 9) by arranging a variable voltage generator (18h, 18v) attached to each deflection coil so that the set-up and adjustment of the equipment and measurement preparations can be performed easily. Moreover, this equipment possesses a displayer (A1, A2, A3, A4) to indicate which position (up, down, right or left) the electron image moved due to the variable voltage, in spite of the fact that the electron image may be damaged temporarily if adjustment is excessive.
