【Abstract】 This paper introduced the model of laser atmosphere propagation measurement,analyzed the noise of laser atmosphere propagation characteristic measurement.According to the analysis of the characteristic and the insufficiency of classical fuzzy enhancement,an improved fuzzy enhancement method was put forward.A pre-processing method which combines the improved method and mean filter was put forward to process laser spot image get from experiment.The results shows that compared with the common pre-processing methods,the new method can enhance the image contrast and improve the image quality effectually.更多还原
