<p><P>PROBLEM TO BE SOLVED: To provide an optical scanner capable of setting a plurality of scan angles and spatial resolutions, which is realized in a small size and with simple configuration. <P>SOLUTION: An optical scanner 12 comprises a light source device 20 composed of a plurality of light sources; a light deflecting element 22 composed of light deflecting elements whose number corresponds to the number of the light sources; and a plurality of enlargement lens systems 26 for scan angle and beam spread angle with different magnifications, individually corresponding to each light deflecting element. By selecting any of the enlargement lens systems, and a light deflecting element and a light source corresponding to the system, a plurality of scan angles and spatial resolutions can be set. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
