A system for optical scanning along one line with fast random access and high optical resolution, composed of: a plurality of first lenslets ( 240 ) constructed for use with a selected media format ( 224 ), the plurality of lenslets ( 240 ) all being disposed in a single row and being spaced apart by a given center-to-center distance; a movable mount carrying the plurality of lenslets ( 240 ), a linear motion actuator ( 241 ) coupled to the mount for moving the mount in a direction substantially parallel to the single row over a distance having a maximum value that is substantially equal to or slightly greater than the given center-to-center distance; at least one light source ( 260 ); a light directing unit ( 234 ) for directing light from the source to any one or two selected lenslets ( 240 ); and a control unit for controlling the light directing unit ( 234 ).
