Embodiment Construction
[0036] Such as Figure 1 ~ Figure 3 As shown, this embodiment involves a UAV terminal laser energy transmission system based on three-level tracking and phase modulation, including: UAV 1, terminal five-axis turntable 2, photovoltaic cell array carrying module 3, and tracking galvanometer Unit 4, spatial optical phase modulation diaphragm 11, collimating beam expanding module 5 and high-power laser 6, wherein: the Gaussian laser first passes through the collimating beam expanding system for collimating and expanding the beam and homogenizing the energy so that the diameter of the spot To reach the appropriate range of coverage of the spatial optical phase modulation diaphragm, and then use the galvanometer tracking device to perform rough adjustment of the light field tracking UAV. Light field, the Gaussian light field of the laser is modulated into an optimal light field suitable for the arrangement of photovoltaic cells, and the fine-tuning and tracking alignment of the ligh...
