[Abstract]:With the rapid development of manufacturing industry, the requirement of testing technology is more and more high in China. At present, the main measuring instruments in the market include grating, inductive synchronizer, laser interferometer, magnetic grating and so on. Among these measuring instruments, the grating is the most widely used. The grating uses precision line to measure the spatial displacement. The concept of time-grating displacement sensor has been put forward by the research group in the laboratory. The spatial displacement is characterized and measured by clock pulse. The displacement sensor has been used in the industrial field step by step. The light field time grating is a new research direction of the time grating. The study of the transmission light field time grating has been completed in the early stage, which proves the feasibility of the light field time grating. In order to expand the application of the project, The research of reflective light field time grating is carried out. The design of optical system and the simulation of light field distribution are an important part of the study of light field reflection time grating. The optical system of light field time grating affects the uniformity and parallelism of light transmission. The uniformity and parallelism of illumination are the important guarantee of spatial modulation of light field time grating. In this paper, the measurement accuracy of the light field time grating is improved. The main research contents are as follows: 1) the measurement principle of the time grating and the light field time grating is studied in depth. Based on the mathematical model, the influence of various factors in the process of light transmission on the measurement is analyzed. (2) from the selection of light source and the luminous characteristics, the light distribution design is carried out to ensure the illumination uniformity of the light source to complete the design of the optical system. The tolerance analysis and formulation of the optical system are completed by ensuring the parallelism of the light emitted from the light source, reducing the divergence angle of the light ray and modulating the intensity of the time-grating of the light-field type, and improving the measuring accuracy of the light-field-type time-grating. Finally, the distribution of light intensity at the moving pole plate and the fixed pole plate of the light field time grid is analyzed, and the spatial modulation effect of the moving pole plate is simulated. The relationship between the light intensity energy and the moving displacement of the fixed pole plate on the detector is plotted by Matlab.
