Application on digital image technology in decentration measuring for objective lens 數(shù)字圖像技術(shù)在中心偏測試儀中的應用
The consumption patter from decentration to concentration is mutually dependent and promoted with that of the economy patter 消費由粗放型到集約型增長,是與經(jīng)濟增長方式由粗放型到集約型增長相互依存、相互促進的。
Based on the relationship between the change of the cornea thickness and optical path length , the ablation profile for the correction of wavefront aberration is presented and simulated on computer . the process of scanning - spot excimer laser is studied and simulated on computer . models for calculation of residual wavefront aberration on situations of lateral decentration and torsional misalignment are brought up 使用改變光程的方法建立起波前像差與角膜切削量之間的關(guān)系,并對像差矯正模型進行計算仿真;深入研究了小光斑準分子激光飛點掃描模型,對飛點掃描過程進行計算仿真;提出了中心偏移和旋轉(zhuǎn)情況下剩余像差計算模型,為定量研究切削中心定位精度對像差矯正的影響提供了依據(jù)。
