ABSTRACT:
The present invention provides an electron holography microscope producing an interference pattern having contour moire lines which is displayed on a cathode-ray tube. With the invention the three-dimensional structure of a specimen can be readily observed on the cathode-ray tube. The electron holography microscope of the present invention comprises a television camera which picks up the interference pattern a straight line fringe output means for delivering a straight line fringe pattern the direction and interval of which are selected at will. Outputs of the television camera and the means are added in a multiplier and the result is displayed on the cathode-ray tube.
