激光扫描技术发展分析

Analysis of the Development of Laser Scanning Technology

随着热可逆记录介质应用范围的日益扩大,如何提高热可逆记录介质的耐久性和在其上进行图像记录或擦除的效率引起了业界的关注,同时,对在热可逆记录介质上进行激光扫描的技术研究也在深入进行中。本文首先介绍了传统的激光扫描控制方法,然后展示通过改变施加的激光光强分布或激光扫描方式的新型技术,这些新的技术有效地减少了在图像记录和擦除过程中对热可逆记录介质的能量积累,提高了热可逆记录介质的耐久性和激光扫描的速度。

With the growing of the application range of the thermo-reversible recording medium,how to improve the durability of thermo-reversible recording medium and the efficiency of the image recorded or erased on the thermo-reversible recording medium cause the concern of the industry,at the same time,study on the laser scanning technology on the thermo-reversible recording medium is continually in progress.In this paper,firstly,the traditional laser scanning control method was introduced,and then the new technology with changing the intensity distribution of laser or laser scanning methods was showed.The new technology can effectively reduce energy accumulation of thermo-reversible recording medium in the process of image recording and erasing,increasing durability of thermo-reversible recording medium and speed of laser scanning.
