Abstract

A technique which automatically adjusts the optical axis of a CCD image sensor with the lens for a linear CCD image scanner is described. The error of the alignment is measured to the magnitude and pulse-width of the detected signal from the linear CCD image sensor, calculating the value of error by computer and driving the stepping motor to achieve the automatic adjustment.
