Experimental study on visual optical monitoring of the atmospheric disturbance of moving objects
Based on a high-precision atmospheric disturbance monitoring method for moving objects, speckle images and various satellite images were used as background, and an experimental study on the atmospheric disturbance caused by an airplane scale model was carried out with the airplane model under the impact of high-pressure air flow. It was verified that the refractive index gradient of atmospheric disturbance was 10-6 by visual optical detection method for atmospheric disturbance of moving objects under the conditions of various background images with different resolutions and different types. The visual atmospheric disturbance information in the same experimental condition was obtained by the traditional schlieren imaging experiment, which can directly display the information of atmospheric disturbance. Through contrastive analysis, the results showed that the atmospheric disturbance information obtained by the visual optical monitoring method was the same as the directly displayed information, so the correctness of the visual optical detection method on atmospheric disturbance in the background of satellite images was directly verified. The results of this paper verified that the correctness of the visual optical monitoring method for atmospheric disturbance of moving objects in the laboratory and the monitoring accuracy of atmospheric disturbance in the condition of the laboratory test.
