Method For Measuring Rotating Scanner Parameters

In some applications, such as laser printing, the scanning mirror is required to work within very severe tolerances, in order to insure good dot alignment and uniformity, which are essential conditions for high level print quality. In the present paper some methods are described, based on optoelectronic devices and a minicomputer data acquisition system, which permits measurement of the relevant parameters of the laser scanner with adequate precision.
