METHOD FOR PRODUCING CO- ORDINATE PLANE- TABLE FOR ELECTRO- OPTIC DIGITIZER

摘要

This method is designed for computer peripheral devices. The electro-optic digitizer plane-table of this method allows for selective interruption of two light beams of different wavelengths. The method includes printing mutually perpendicular lines in two colors. The first group of lines absorbs light of a specific wavelength, which is generated by one photo emitter, and the second group of lines absorbs the light radiated by both photo emitters. The printing is done on a shiny, strongly reflective aluminium vaporized polyester folio.<IMAGE>
