1. An imaging system comprising: a microscope objective; a time delay integration camera configured to produce an image a pixel at a time along a line at a time from scanning of a sample along a scanning axis normal to an axis of rotational symmetry of the microscope objective wherein said pixels are clocked out at a rate different from scan rate of said pixels; and a lateral offset system along the axis of rotational symmetry, the lateral offset system configured to independently shift the position of the image in the camera in a plane normal to the scanning axis.
