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.
用電子束逐行掃描方法刻蝕衍射光學元件的浮雕結搆精度高而速度低。
Display systems must"look" for this negative going edge in order to identify the moment intime when to re-sync the raster scan process.
顯示系統必須“找到”這個負極性的下降沿，以便確定重新同步光柵掃描進程的時刻。
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.
在光柵掃描顯示器上模擬傳統PPI雷達顯示器，不可避免地會遇到直角坐標與極坐標轉換的問題，而雷達廻波信號從極坐標到直角坐標的變換是決定系統性能的關鍵。
