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Kmeans聚类,能够实现很好的准确度。Frequency stability and precise control of lasers are critical for many applications,including optical communications,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.
