本文从动态光电显微镜的成像理论和实验分析出发,阐述了最佳狭缝宽度的选择原则,进行了公式推导,并给出了选择结果;证明了激光比长仪工作台运行时的起伏及调焦误差引起的离焦是影响重复定位精度的主要原因;同时也证明了离焦与倾斜照明的综合影响是造成正反测不一致的主要原因;针对上述降低定位精度的主要因素,提出了改进与提高的途径和措施。
Based on the theory of imaging and experimental analysis of dynamic light microscope, the principle of selecting the optimal slit width is expounded, the formulas are deduced and the selection results are given. The fluctuation and adjustment The defocusing caused by coke error is the main reason that affects the repeatability of positioning accuracy. It also proves that the combined effect of defocusing and tilting illumination is the main reason for the inconsistency between positive and negative measurement. According to the above mentioned main factors to reduce the positioning accuracy, Ways and means of improvement
