## 多光纤干涉图像的数值模拟及实验

Numerical Simulation and Experiment of   Multi-fiber Optic Interference Image
Abstract: As a new method of optical sensing and measurement, in order to realize the accurate  3-D measurement of the object, an optical fiber projector based on optical fiber interference was introduced. It is made of multi-optical fibers in space in  different combinations of interference, resulting in a space form a variety of interference pattern, the interference pattern constitutes a multifunctional fiber optic interferometric projector, and gives a theoretical  model of space optical fiber composite structure of interference image and computer simulation results were compared, constructed the experimental system is to get the  result. The impact of the location parameters of optical fiber projector on interference pattern was discussed. It is of great significance to the study design of optical fiber image projector and its practical application.
Key words: Optical fiber projector; Interference image; Numerical simulation; 3-D measurement
