<p>Photoconductive light pen is used for writing and drawing on sensitised material and is composed so as to produce a point resolution image. The pen is preferably for use in a raster plotter and can correct irregular errors or blurring in that it is bunched on the image side of the material, with the free fibres on the other side precisely allocated to the individual points forming the picture. The picture is preferably reproduced on a screen and transmitted by a light pen. The picture should be broken up electronically into strips which are then transmitted by light pen fibres grouped to form a straight line on the image side.</p> |
