Title:
ビーム案内を有するリソグラフ及び記憶媒体にデジタルホログラムを生成する方法
Document Type and Number:
Japanese Patent JP2004523805
Kind Code:
A
Abstract:
Producing a digital hologram-in a storage medium includes: (i) focusing a write beam onto the storage medium; (ii) moving the write beam two-dimensionally relative to the storage medium; (iii) focusing a scanning beam onto a beam-guiding mask having a plurality of tracks; (iv) moving the scanning beam two-dimensionally relative to the mask, the movement of the scanning beam being coupled with the movement of the write beam; (v) generating a position control signal when the position of the scanning beam deviates from the scanned track by a predefined value; (vi) controlling the position of the write beam on the storage medium with the aid of the position control signal; and (vii) writing the hologram by introducing radiation energy point by point, the intensity of the write beam being controlled as a function of the position of the write beam on the storage medium.
