Research On Spatial Noise Of High Resolution Thermal Infrared Imaging System

The application of high solution thermal infrared imaging system highly relies on the signal to noise ratio (SNR) of instruments to acquire images. To enhance the imaging quality of the thermal infrared imaging system, the noise model for images of the thermal infrared imaging system has been analyzed. Spatial noise elimination method is proposed, including the results of the comparison between different methods. With combination of the testing data of the thermal infrared imaging system, it is showed that the method mentioned in this paper can really enhance the spatial -domain NETD and spatial resolution of images effectively.
