Key highlights
The Beam Divergence Control (BDC) module is an optical device designed for laser communication terminals. By optimally varying the beam divergence angle through the movement of the built-in lens, it enhances the efficiency of the PAT (Pointing, Acquisition, Tracking) process in free space optical (FSO) communication. This product was developed as a prototype in collaboration with the National Institute of Information and Communications Technology (NICT), and our company has successfully achieved miniaturization and space compatibility.
Key features
- The beam divergence angle is controlled in real-time to achieve the optimal angle based on the communication distance and error, thereby contributing to the high efficiency of the PAT process.
- By utilizing photographic zoom lens technology, we have developed a high-precision lens drive system that operates effectively in a space environment.
- Designed for integration into LCT, our system achieves low SWaP (Size, Weight, and Power Consumption).
