Abstract
This paper describes a technique which automatically adjusts the optical axis of CCD Image sensor with the lens for Linear CCD Image Scanner. The error of the alignment is measured to the magnitude and pulse width of the detected signal from the linear CCD Image sensor. Caculating the value of error by computer and driving the stepping motor to achieve the automatic adjustment.
