METHOD AND ARRANGEMENT FOR OPTICALLY DISPLAYING CHARACTERS CONSTITUTED BY RASTER LIGHT SPOTS ON A PROJECTION SURFACE

摘要

A method of increasing the flicker-free information in dynamic projection of image spots of an image in which the image-spot frequency is limited. The character forming raster of light spots consists of a meshed light spot series which is repeatable at approximately 50 times per second. The position of the first light series is chosen such that the full characters are visible after completion of all the series. Arbitrary energization of the separate image spots allows for a reduction of picture frequency and a flicker-free display.
