In this study, the aim is to investigate the basic characteristics and the tolerance of linear scanning of zone plates by means of active scanning, so as to provide adequate evidence in fabricating specific HOEs. The holographic zone plate can by means of duplicating the technique and manufacturing process apply to implement the fθ image analysis. The extended zone plate has the characteristics of linear scanning, enabling the scanning surface to achieve the effect of linear motion at equal velocity. This will avoid the trouble of correcting linear tolerance when installing the electronically compensated system. From the experiment results, the extended zone plate has a good effect in linear scanning and focusing.
