納米時柵誤差分析與實驗研究
[Abstract]:Nano-time grating sensor is a new type of nano-scale displacement measuring instrument developed by our country. It is characterized by a large range and high precision. According to the principle of time grating measurement, the measurement error can be caused by the deviation of sensor installation, the realization of structure, the change of substrate processing and working environment, etc. This restricts the further improvement of the precision of the nanogrids sensor. At present, my team also lacks the analysis and summary of this problem in the basic research of nanometer time gate sensors. In order to study the cause of error and the rule of influence on measurement accuracy, the theoretical system of nanometer time gate sensor is developed, the measurement precision of nano time gate sensor is improved, and the performance of current data analysis experiment system of nano time gate sensor is optimized. Improve team experiment efficiency. Based on the measurement model of nanometer time gate sensor, this paper studies the error of nano time gate sensor in the working process by means of mathematics and physics, and does the following work: 1. According to the expression of nanoscale gate traveling wave, the measurement error model caused by the variation of standing wave parameters is established, and the amplitude is not equal and the phase is not orthogonal in the variation of standing wave signal parameters. Variation of error in three cases with high frequency interference. 2. The front-end original signal processing circuit and FPGA digital signal processing circuit are optimized. A set of software system based on C # language, including real-time processing, image recognition, FFT spectrum analysis, adaptive coordinate system drawing and so on, is developed, which can be used in the experiment of nanometer time grid error analysis. Through the experimental research, the stability of the improved experimental system is evaluated, and the influence of various errors on the measurement accuracy is determined: if the two standing wave amplitudes are not equal, a second harmonic error will be produced. If the two-way traveling wave time is not orthogonal, a fundamental frequency and second harmonic error will be produced. If n-th high frequency interference is introduced, it will bring a sub-harmonic error to the measurement error. At the same time, the precision experiment is carried out, and the simulation experiment of dynamic separation and correction of the original error is carried out. The accuracy of the experiment is achieved in the range of 200mm.
