摘　　要：光栅的成象效应是光栅被点光源或扩展光源照明后自成象的一种特殊效应。该文应用傅里叶光学原理对扩展光源照明下光栅的成象特性作了分析,并由此设计出一种新型的光栅成象型位移传感器。The imaging effect of grating is a special effect of self-imaging of grating illuminated by point source or expansion source. Basedg on Fourier optical principle, the imaging property of grating illuminated by expansion source is analysed in this paper.Hence an innovative grating imaging displacement sensor is designed.
