- The UAV sprayer is efficient, easy to use, and safe, making it a valuable tool in agriculture, especially for increasing farmers' profits.
- Recent studies focused on UAV sprayers have primarily targeted crown-shaped plants, with a gap in research on garden plants.
- This experiment investigated the effectiveness of UAV sprayers on garden plants, determining optimal conditions for droplet deposition, which is crucial for pest control and the use of growth regulators.
This work presents a simple microwave photonic downconversion channelizer based on multi-wavelength laser sources. The design of two laser diode (LD) arrays enables signal multiplexing and simultaneous multichannel downconversion processing, which provide stable, relatively flat, and strong multi-frequency combs. A proof-of-concept experiment was taken, showing that 14.
