Long-range Air Transport of Dioxin from North American Sources to Ecologically Vulnerable Receptors in Nunavut, Arctic Canada

Color imaging apparatus is disclosed for forming a beam of light having three separate intensity modulated color components. The beam is line scanned across the surface of a photosensitive surface for recording. Three separate color component light modulating channels are provided. Each channel includes an electro-optic modulator responsive to a voltage signal for modulating the intensity of collimated light passing through it in accordance with the desired intensity of a color component. Dichroic mirrors separate the light from each channel into an intensity modulated color component. These intensity modulated color components are combined into a single beam which is line scanned across the surface of the photosensitive member.
