摘要： Image input and recording apparatus are disclosed which have a resolution capability of conventional photographic film recorders and which accommodate color image generation by simultaneously or separately scanning beams (102, 104, 202) differing in color and black and white image generation by scanning one beam. A glass plate (38) made of fibers (181) in combination with a lens (34) and a spotsize selector (54) including glass plates (60, 62) set at opposing angles (64) maintains constant beam spot size. Apparatus orthogonality errors uncorrected by optical elements, non-linearities, and beam power drift are corrected using electronics including look-up tables (U4, U6, U9, U10) and a digital frequency synthesizer (U8). Software accepts data in standard formats or formats specifically for the apparatus and preforms image data processing. The input apparatus includes photodetectors (108, 112, 116) opposite the plate (38) from beam sources (100, 200). A method for converting image focus locus shape is also disclosed.
