A multi-polygon laser scanner system has been developed by using a shrink fitter, in order to produce a new laser direct imager having an ultra wide scanning width and high resolution. The shrink fitter is a new machine element which is cylindrical-shaped and made of plastic materials. This is developed to connect the two machine elements that have different thermal expansion coefficients with a shrinkage fit. In this joining method, the optical axes of the lenses coincide with the axis of the lens-barrel. The positioning accuracy of the lenses in the lens-barrel did not change at any temperature since the shrink fitter sufficiently expanded or contracted in the radial direction to compensate the change in interference. Therefore, the beam spot became very fine all over the wide scanning width at elevated temperature. In this study, we applied laser scanner units using the shrink fitter to the multi-polygon system, which arranged these units in a line. The performance of the new laser direct imaging system was confirmed experimentally.
