摘要:
A hologram array is utilized having a plurality of adjacent holograms which are illuminated at an acute angle by laser diodes. Each laser diode output is modulated by an information source such as a computer output or the like. The outputs of the hologram array leave the hologram at an acute angle such that the focal points of the beams leaving the hologram array are focused on the object surface (a photoreceptor or the like). Closely controlled spacing of the outputs of the holograms is achieved by appropriate spacing of the holograms. In order to provide two-dimensional scanning, an appropriate combination of spherical and cylindrical lenses may be utilized together with a moving polygonal mirror to move the output beams from the hologram across the surface of the photoreceptor.
