Improvement on Milikan's Oil-Drop Experiment Based on Image Acquisition Card
Teng Jian · Journal of Shenzhen Polytechnic · 2012
The paper introduces the improvement on traditional Millikan's oil-drop instrument.By using image acquisition card,oil-drop image is captured for computer processing.Via computer programming,this card can catch experiment images dynamically and measure experimental data automatically.With improved mapping method,oil-drop charging amount is 1.598×10-19C and error is reduced from the original 1.87% to 0.87%.The accuracy of the experiment is enhanced greatly and the experiment is characterized by repeatability,simple operation and easy measurement.
