A parabolic concave mirror can converge parallel light rays to its focus, and also collimate light rays that pass through its focus
拋物面凹鏡會把平行而來的光線聚集在一點焦點，亦會把源自焦點的光線平行向外反射。To reduce the marking distortion, using the vertical 2 - dimension galvanometer distributing and f field lens focalize, the distance of the second galvanometer to the machining plane is the focus f. to avoid too hign temperature to distroy the resonance cavity because of too long marking time, cooling system and self - protector is used in the design
為減少打標畸變，採用垂直二維振鏡分佈， f物鏡聚焦，將激光束經第二個振鏡反射後到加工平面的距離為焦距f ，為了避免打標時間過長，溫度過高破壞諧振腔，在設計中加上冷卻系統和自我保護裝置。Abstract : based on the electronic focus technology development of state - of - the - art, the paper suggested a complete apparatus s cheme ofauto - focus based on sspd ( self - scanned photodiode array ) and 8098 singl e chipprocessor, giving out a focus criterion algorithm based on image high freq uencystatistics. the function of auto - focus of both reflected and transparent o pticalmicroscope was realized. meanwhile some corresponding problems such as sta bility of lightsource, step motor driving etc. were also discussed, which greatly improved the accuracy andreliability of the system
文摘:在介紹與分析了國內外電子調焦系統的技術發展與現狀的基礎上，提出了一種基於sspd （自掃描光電二極體列陣）與8098單片微處理器自動調焦的整體技術方案，給出了基於圖像高頻成分統計的聚焦判識演算法，在此基礎上實現了反射式與透射式光學顯微鏡的自動調焦，同時對系統的可靠性有關的其它相關問題如光源穩定性、步進電機驅動等問題也進行了討論。
