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.
