An dithering system for implementation of a microscan that dithers an image on an array of sensing elements that defines an image plane by moving one or more lenses which displaces the image focused on the image plane. Piezoelectric positioners are provided to move the one or more lenses a predetermined amount and on a predetermined plane parallel to the image plane so that the image focused by the lensing system on the array of sensing elements is displaced on the image plane by the movement of the lensing system. As the lens is moved by the positioners and thus the optical axis of the lens, the image passing through the lens is also moved on the image plane. Moving the lens horizontally and vertically or in a predetermined pattern provides dithering of the image so that microscanning can be employed.
