PURPOSE:To obtain a device in which a diffracted image consisting of duplicatedly written lines can be displayed without carrying out lining after photographing by douplicating a plural number of parallel marker lines to form the diffracted image which is displayed on the cathode-ray tube. CONSTITUTION:Diffracted images formed in an electric microscope 1, are converted into electric signals by means of an image pickup device 2 before being supplied to a picture-signal-storing device 4 and stored in it. When the stored electric signal is read out and supplied to a cathode-ray tube 11, a diffracted images containing many diffraction spots are displayed on the cathode-ray tube 11. At this point, an electric pen 16 is moved on a tablet 15 so that the positions of luminous points coincide with the spots thereby storing positional signals in a memory 19. In an operation-controlling circuit 20, signals for indicating luminous lines are produced according to data representing the coordinates of the positional signals, then supplied to a parallel-luminous-line-displaying-signal- producing circuit 24. As a result, an image in which luminous lines exist along a grid formed by diffracted spots, is displayed on the cathode-ray tube 11. |
