Abstract:
A scanner apparatus comprising:a light source array that emits a plurality of light beams;a collector that collects said plurality of light beams emitted from said light source array and transmits the light beams to a limited space region from which the light beams are focused on a scanning surface;a collimator located at said limited space region, said collimator collimating said light beams to form a plurality of collimated light beams; anda spatial filter that includes a first portion that absorbs or blocks light surrounded by a second portion that reflects or transmits light so that the spatial filter imparts modulation to a spatial spectrum of said collimated light beams formed by said collimator, said spatial filter located at a position where optical axes of the collimated light beams intersect each other.
