To Measure the Thickness of the Glass
with Michelson Interferometer
Abstract: Michelson interferometer for measuring physical quantities is recognized the highest accuracy for detecting means in this stage. However, due to the long-term use of the instruments, there may be bring some problems in the measurement process, such as the errors of the measurement results, and impacted its accuracy. In this paper, using a Michelson interferometer to measure the thickness of the glass side and using other methods to calculate the thickness of a comparative analysis of the accuracy of the Michelson interferometer. At present, there were experiments with the Michelson interferometer to measure the thickness and refractive index of the experimental parallel transparent objects, but they did not analyze the accuracy of the Michelson interferometer, calculated with an accuracy error analysis of the experimental results and the accuracy of great help.
