FAST AND HIGH RESOLUTION RASTER OUTPUT FSCANNER |
摘要 |
A high-speed, high-resolution raster output scanner having a single source (9) beam; a beam splitter (25) for separating the beam into at least two separate and parallel writing beams; an acousto-optic modulator (40) having a substrate sized to provide a separate modulation channel for each writing beam to pass through without intruding into the other modulating channels; an rf transducer (44) for each writing beam for generating separate acoustic waves in each modulation channel of the substrate; a control circuit for simultaneously intensity modulating the writing beams by the rf output of all transducers in accordance with separate lines of image signals; and optical means (91) for simultaneously projecting the intensity-modulated writing beams at points two lines apart on a record member, the optical means including a prism for scanning the writing beams across the record member so as to write two or more image lines at a time. |
