【摘要】 对微弱重复信号的检测采用数字累积平均法是一种极有效的技术。实验采用Apple-Ⅱe型机实现了对光纤瓦斯传感系统中4组微弱光信号检测,明显改善了检测系统的功能。本文介绍了系统硬件、软件设计以及有关问题。更多还原

【Abstract】 A technique using a nvcro-computer (Apple-Ⅱe) to process four groups of weak optical signals in an optical fiber gas sensor system is introduced. It improves the function of this detection system obviously. The desings of the hardware, software and some relative problems are also introduced.更多还原
