Detailed explanation of optical fiber FPV UAV technology

1. Technical basis and principle

Optical fiber FPV(First Person View) UAV technology is an innovative technology that combines optical fiber communication technology with UAV technology. By using optical fiber as a high-speed and low-delay data transmission medium, this technology realizes the real-time transmission of high-definition video signals shot by unmanned aerial vehicles back to the ground control station, providing pilots with an immersive flight experience. Optical fiber transmission has greatly improved the performance and application range of FPV UAV because of its ultra-large bandwidth, super anti-interference and extremely low delay.

2. Optical fiber transmission system

Optical fiber transmission system is the core component of optical fiber FPV UAV, including optical fiber transmitter (UAV end) and optical fiber receiver (ground end). The transmitter is responsible for converting the video signal captured by the camera on the UAV into optical signal and transmitting it to the ground through optical fiber. The receiver is responsible for converting the optical signal into an electrical signal and decoding it into a video signal to be displayed on the display screen. Optical fiber transmission system not only supports high-definition or even ultra-high-definition video transmission, but also can effectively resist electromagnetic interference and ensure stable signal transmission.

3. Real-time video transmission

Optical fiber FPV UAV can realize real-time video transmission without delay, which is one of its greatest advantages. Through the high-speed transmission ability of optical fiber, the pictures taken by UAV can be displayed on the screen of ground control station instantly and accurately, so that pilots can accurately judge the flight state and environmental changes and make rapid responses. This is especially important for performing complex flight missions, accurate shooting and other scenes.

4. Design of UAV platform

The platform design of optical fiber FPV UAV should fully consider the integration and layout of optical fiber transmission system. On the one hand, it is necessary to ensure the stable connection of optical fiber cables and avoid signal interruption caused by vibration or swing during flight; On the other hand, it is necessary to optimize the aerodynamic performance of UAV, reduce flight resistance and energy consumption, and improve flight stability and endurance. At the same time, it is also necessary to consider the load capacity of the drone to ensure that it can carry enough optical fiber transmission equipment and high-definition cameras.
