光纤光栅视觉系统的研制

A Kind of Vision System with Optical Fiber Grating

利用光学衍射原理，研制成了光纤光栅衍射屏，并与计算机神经网络相结合，开发了一种识别立体形状的视觉系统．本文介绍了光纤光栅的设计原理及计算方法，给出了系统的总体结构及工作原理，完成了三棱柱、三棱锥、四棱柱、四棱锥和球等立体形状学习与识别，并讨论了实验结果．

A new kind of optical fiber grating screen is perpared successfully according to the optical diffraction law.By combining it with computer nerve network,a kind of vision system with three-dimensional resolving is devoloped,especially for several cases such as three-prism、four-prism、ball,is tested.
