[0002] Aerial remote sensing cameras are widely used in the aviation field. They can obtain large-scale, high-resolution ground images and data through aerial platforms for use in map making, resource exploration, environmental monitoring and other fields. However, in actual applications, aerial remote sensing cameras are often affected by severe weather conditions, such as fog and rain, which cause fog or water vapor on the camera mirror, affecting the clarity and quality of the image, and may even cause the camera to fail. Therefore, an effective defogging device is needed to solve this problem.

[0003] Camera defog technology is a solution to the above problems. The traditional defog method mainly uses water washing and wiping, that is, cleaning the camera mirror by manual or automatic devices to remove the attached fog or water vapor. However, this method has some defects, such as poor defog effect, residual water vapor on the mirror surface, which is difficult to completely remove, and there is also a risk of damage to the camera mirror surface. It also requires frequent maintenance and manual operation, which increases the cost of use and human resource consumption. Utility Model Content
