prism-angle error
解釋
棱鏡角差誤-
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。 -
This paper analyses emphatically the position error and manufacture error of critical - angle prism the position error and aberration of object lens the position error and manufacture error of the polarization beam splitter the position error of the detector, and come out their relations
著重分析了臨界角棱鏡位置誤差與製造誤差;物鏡的位置誤差與像差;偏振分束棱鏡的位置誤差與製造誤差;探測器的位置誤差等對離焦誤差信號的影響,並給出了理論曲線。
