CCD 摄象法测量有机聚合物光波导传输损耗

CCD Camera Photographing in Detecting the Propagation Attenuate Coefficient of Polymer Waveguides

研究了一种测量有机聚合物光波导传输损耗的方法——ＣＣＤ摄象法．通过对波导传输线进行数字成像，根据传输线上的光强分布拟合出光强传输衰减曲线，计算出波导的传输损耗．与传统方法相比，本方法具有操作简便，测量准确的优点．

CCD camera photographing, a new method to detect the attenuate coefficient of the guided wave propagation in polymer waveguides, is discussed. By way of taking a digital photograph of the propagation line of the waveguides, the attenuate coefficient can be calculated after imitating the radiation intensity distribution of the propagation line into an attenuate curve. Compared with other detecting methods, it is more convenient and accurate.
