Webbweak feedback, the OFSMI signals are strictly band limited in nature, with the cut-off frequencies being the vibration frequency and the fringe frequency respectively. Also increasing broadens the bandwidth but has little influence on the bandwidth of the signal. At moderate feedback, the OFSMI signals are still band Webb29 maj 2009 · Abstract: This paper studies the behavior of optical feedback self-mixing interferometric (OFSMI) systems, where the semiconductor lasers operate at a single mode (perturbed external cavity mode) with a large optical feedback factor C .

Webb【摘要】:光反馈自混合干涉(Optical Feedback Self-Mixing Interference,简称OFSMI)效应是指激光器输出光经外部反射体反射或散射后,其中一部分光又反馈回激光器谐振腔,反馈光与腔内光相干涉,从而调制激光器输出光功率的现象。 由于OFSMI信号中含有外部反射体运动信息,所以OFSMI系统可以用于外部反射体位移测量。 OFSMI位移测量系统和传统双 …

Webb由此可以看出,OFSMI法是一种可靠的线宽展宽测量方法。 其与线宽法相比有以下优点: (1) OFSMI法不依赖激光管的类型,而线宽法由于激光器本身的自发辐射通常用于垂直腔表面发射激光器 (VCSEL); (2) 不需要诸如光谱仪等昂贵的实验设备,整套装置结构简单,成本低; (3) 量程大、精度高且抗噪声性能好。 [6] Henry C H.
