Abstract
This paper describes a method for displaying pictures or drawings by luster scanning method. An arbitrary picture film can be processed for a digital coding method which will minimize the number of code levels required to describe a picture.
Ordinary drawings or moire fringe photographs consist of binary data with “black” and “white”, where the code levels are limited within the two. An introduction of the partial differentiation through the Fast Fourier Transform has led to the calculation of moving the side band spectrum in the two-dimensional Fourier transform transmitted over the channel of luster scanning binary data series. For displaying the successively changing patterns equi-moving coordinates are dotted by a dot-printer machine which is better to draw such as scanned pictures than by a conventional computer aided drafting machine or X - Y plotter.
This method shows a good merit for displaying not only linear but also non-linear change phenomena in the engineering fields.
