该文运用抽样理论分析了光纤传像元件的传像机理，导出了光纤传像元件分辨率测量中所产生的莫尔条纹线对数与原鉴别率板图案线对数之间的关系。当输入鉴别率板图案的线对数高于１／２光纤传像元件抽样频率时，就会产生莫尔条纹现象，两者线对数之和为光纤传像元件的抽样频率。给出了极限分辨率判别的方法，鉴别率板图案像中线对最密的一组判定为光纤传像元件分辨极限，并从实验上验证了理论分析结果
This paper analyzes the transmission mechanism of the optical fiber imaging element by using the sampling theory and deduces the relationship between the logarithm of the moire stripes and the logarithm of the pattern of the original identification plate in the resolution measurement of the optical fiber imaging element. The moiré fringe phenomenon occurs when the number of pairs of input discrimination plate patterns is higher than the sampling frequency of ½ fiber-optic imaging element. The sum of the logarithm of the two is the sampling frequency of the fiber-optic imaging element. The method of discriminating the limit resolution is given. The most compact set of discriminating plate pattern like center line pairs is judged as the resolving limit of optical fiber imaging element, and the result of theoretical analysis is verified experimentally
