Sandia 国家实验室运用带有磁性半导体的光导纤维技术研制出了可用于测量时间为亚微秒数量级的探测器。利用光导纤维具有以下两大优点:第一,纤维不导电,可在电噪声环境中进行测量,而常规的测量方法将受到环境的干扰;第二,光纤具有很大的带宽(数千兆赫),因此其测量时 Sandia National Laboratory uses optical fiber technology with magnetic semiconductors to develop detectors that can be used to measure orders of magnitude on the order of sub-microseconds. The use of optical fibers has the following two advantages: First, the fibers are non-conductive and can be measured in electrically noisy environments, whereas conventional methods of measurement suffer from environmental disturbances. Second, optical fibers have a large bandwidth (several gigahertz) , So its when measured
