raster scan

基本解释

The relief structure of diffraction optical element can be written precisely but very slowly with the raster scan mode bye-beam.
用电子束逐行扫描方法刻蚀衍射光学元件的浮雕结构精度高而速度低。
Display systems must"look" for this negative going edge in order to identify the moment intime when to re-sync the raster scan process.
显示系统必须“找到”这个负极性的下降沿，以便确定重新同步光栅扫描进程的时刻。
The issue of polar coordinate-orthogonal coordinate conversion, which is a key factor of the system, may be encountered inevitably as simulating traditional PPI radar indicator on raster scan display.
在光栅扫描显示器上模拟传统PPI雷达显示器，不可避免地会遇到直角坐标与极坐标转换的问题，而雷达回波信号从极坐标到直角坐标的变换是决定系统性能的关键。
