摘要
提出了一种新型的基于声光可调滤光器(AOTF)的便携式光纤损耗光谱检测系统。建立了光纤损耗光谱检测的数学模型和检测系统总体结构。该系统利用声光可调滤光器的电可调谐特性,采用DSP进行智能化控制,实现对光纤中信号光的快速光谱扫描,测量出被测光纤对不同波长的信号光的衰减特性。最后给出了实验结果和讨论。
A novel portable system for optical fiber attenuation spectrum measurement with accousto-optical tunable filter （AOTF） technique is presented. The mathematic model and the scheme of attenuation spectrum measurement are proposed. With the advantage of the AOTF＇s electric tunable characteristics, the measurement system can automatically control spectrum＇s quick scan and detect the optical fiber＇s attenuation characteristics with different wavelength by intellectualized DSP. The experiment resuits are given and discussed.
