Abstract
This study focuses on saturated inference of low-energy laser on the thermal imager and quantitatively analyzes laser power densities and the corresponding saturated laser spots at different incident angles by taking into account the effects of interference laser, atmospheric turbulence, the lens and the photoelectric detector. The relative position of the laser spot on the photosensitive surface on the detector of the thermal imager from the target image is adopted as the evaluation index of laser-induced saturated interference effect. According to the present results, at an incident angle of 0, the target image is partly or completely covered by the interference laser spot, with obvious interference effect and low required laser power. As the incident angle increases, the interference effect is significantly affected and the interference effect is lower than the condition at an incident angle of zero. The interference can be achieved by controlling both size and position of the laser spot.
