摘要
激光器的频率稳定性和精确控制对于许多应用来说至关重要,包括光通信、光谱分析、激光加工和科学研究.针对温度等环境因素容易导致激光器的激光频率变化,为此设计了一种监控方法,能够快速地监控不同环境干扰下的激光的频率变化.根据Talbot成像,从单个视角通过GLCM特征提取,对特征数据使用改进后的T-EWNMF-L1 处理,使用K-means聚类,能够实现很好的准确度.
Abstract
Frequency stability and precise control of lasers are critical for many applications,including optical communi-cations,spectral analysis,laser processing and scientific research.In response to the fact that environmental factors such as temperature can easily lead to laser frequency variations in lasers,this paper designs a monitoring method that can quickly monitor the frequency variations of lasers under different environmental disturbances.Based on Talbot imaging,good accuracy can be achieved by GLCM feature extraction from a single viewpoint,and the feature data are processed using the improved T-EWNMF-L1 using K-means clustering.
