A two-dimensional light-modulating fine aperture array apparatus includes
a spatial light-modulating unit for adjusting quantity of incident light
by using a plurality of light amount adjusting cells (liquid crystal
cells or micromirrors) arrayed in matrix form, a two-dimensional
microlens array having microlenses which focus light beams passing
through the light quantity adjusting cells, and a highly efficient
two-dimensional fine aperture array. The light is emitted through the
fine apertures by connecting the two-dimensional light-modulating fine
aperture array apparatus with a light source unit. A scanning unit moves
in the x and y directions to perform a scanning process on a surface of a
recording medium by using the light emitted from the apertures.
