Abstract
An optical scanner that employs a pulsed light source that is synchronized to the scan position by a position encoder and a pulse control system. Such a scanner has an improved image sharpness and improved image registration. Moreover, a pulsed light source in a scanner of the present invention is more efficient and uses less power, which results in various cost and power savings. Such a scanner is capable of operating off a smaller power source (battery) and is capable of running for longer periods of time off a battery than scanners with a light source that is on during the entire scanning process.
