解釋
雙孔透鏡-
This paper analyses the critical angle method that often use in focus detected. we receive two relations, the first relation between refractive index of the critical - angle prism and focus - error signal ; the second relation between numerical aperture of object lens and out - of - focus error signal
本文針對伺服系統中常用的調焦方法-臨界角方法進行了分析，理論上得到臨界角棱鏡的折射率、物鏡的數值孔徑與離焦誤差信號的關系。 -
It was based on the principle of laser confocal microscope. and the two - dimensional scanning configuration was adopted by the optical scanner and the telecentric linear imaging objective lens of large numerical aperture to realize x - direction ' s scanning, and the conventional mechanical method using linear driver and linear guide track to y - direction ' s. the experiment results indicate that the device can run smoothly and rapidly, be operated easily and detect fluorescence effectively
儀器基於激光共焦顯微鏡的理論，採用振鏡和遠心線性成像物鏡實現x向掃描；精密導軌和步進電機實現y向掃描的檢測儀，經驗證，掃描儀具有快速、操作簡單、檢測晶元能力良好等特徵，有望彌補市場的空缺。
