摘要： A structure with fine details, such as a periodic signal, is displayed on a raster display. To avoid aliasing due to an interference between the details and the columns and row pattern of the raster display each of the points representing the structure to be displayed is allocated to pixels in adjacent columns and/or rows. Allocation occurs by means of a stochastic procedure in which the probability to allocate a point to a pixel is dependent on the position of the point with respect to the pixel. Accumulated pixel-values are converted into a limited number of grey-values by means of an additional procedure that allows for fixed proportions of the pixels to have the same grey-value.
