| 摘 要： | 本文报道了关于相干柔软光纤传象束(FIB)串象特性的研究.提出一种采用定标的光学视频系统定量测量相干柔软光纤传象束串象率的新方法.在光纤传象束的输入端,借助高精度的光学耦合系统,使光线仅对单根光纤输入耦合,而在传象束的输出端,由CCD阵列相机对被激光纤作大面积范围的检测.并且,测量了光纤传象束的静态调制传函数(MTF),用于描述串象率对传象束传象特性的影响,比较了多种传象束样品的测量结果.

| Abstract: | A research for crosstalk of coherent flexible image fiber bundles is reported. The theoretical expression on crosstalk is got. This paper describes a new technique to quantitatively measure crosstalk in coherent image fiber bundles using a calibrated optical video system. At the input end of the fiber bundle,light is coupled into only one single fiber. At the output end,a large area around the excited fiber is monitored using a video CCD array. Additionally,static MTF measurements together with visual inspection was used to correlate the crosstalk to the imaging properties of an optical fiber bundle. Comparison between different samples resulted by the experimental measurements. |
