高速传输的信息网中，需要有高速的信息交换与之相适应。用光交换代替电交换，已是人们的共识且正在致力于这方面的研究。光纤列阵是光交换模块的Ｅ／Ｏ接口，精度要求很高，需要有精密的检测跟踪，才能保证其研制精度。用ＣＣＤ摄像头成像，送入ＰＩＰ图像板，经计算机软件处理控制进行检测，取代常规的机械检测，精度可达１μｍ，甚至更小，方便适用，能够满足较高精度的科研检测要求。
High-speed transmission of information networks, the need for high-speed exchange of information and adapt. The exchange of light exchange instead of electricity, is already a consensus and is committed to research in this area. Optical fiber array is the optical switching module E / O interface, high precision, the need for sophisticated detection tracking, in order to ensure its development accuracy. With CCD camera imaging, into the PIP image board, the computer software processing control to detect, instead of conventional mechanical testing, the accuracy of up to 1μm, or even smaller, convenient and suitable to meet the high accuracy of scientific research and testing requirements.
