raster scan

基本解釋

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(xué)元件的浮雕結(jié)構(gòu)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(tǒng)必須“找到”這個(gè)負(fù)極性的下降沿，以便確定重新同步光柵掃描進(jìn)程的時(shí)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(tǒng)PPI雷達(dá)顯示器，不可避免地會(huì)遇到直角坐標(biāo)與極坐標(biāo)轉(zhuǎn)換的問題，而雷達(dá)回波信號(hào)從極坐標(biāo)到直角坐標(biāo)的變換是決定系統(tǒng)性能的關(guān)鍵。
