摘要： A printing-plate mounting-position instruction system instructs a worker where to mount a plurality of printing plates in a rotary printing press. The system includes a controller, a reader, a judging device, and a display device. The controller creates assignment information for assigning printing plates to mounting positions on each of plate cylinders used in each of printing units on the basis of production instruction information. The reader reads a mark on a printing plate for printing-surface information. The judging device is connected to the controller and the reader and collates the assignment information received from the controller and the printing-surface information received from the reader, thereby judging the location where the printing plate is to be mounted. The display device displays the result of the judgment.

摘要： A real-time holography system includes a matrix liquid crystal display, as used in a liquid-crystal television set, for producing a hologram. An image of an interference-fringe pattern caused by an object light wave and a reference light wave is converted into a video signal by a CCD camera, and the image of the pattern is reproduced on the display on the basis of the video signal. Therefore, a three-dimensional image can be reconstructed in real-time by making a reference light wave on the display.
