Laser remote sensing detection technology has the advantages of fast information transmission speed, high precision and long-distance detection, which can well make up for the shortcomings of seismic exploration in areas with complicated terrain, such as difficult construction and slow seismic data acquisition. In the previous study, the wavefront sensor, with its high sensitivity, high detection efficiency and off-axis detection, was used in the laser remote sensing detection of seismic waves, and a laser remote sensing detection system was constructed to explore the relationship between the ground amplitude and the spot measured by the wavefront sensor. In order to carry the detection system to the UAV and achieve the transformation from static detection on the ground to dynamic detection in the air, this paper designs an adaptive optical antenna based on FPGA, aiming at optimising the reception effect of the laser remote sensing detection system on the echo signals. The adaptive optical antenna achieves adaptive tracking and zoom by negative feedback adjustment mechanism, and makes real-time adjustment according to the received signal quality.
