Active vibration isolation system to improve free space optics communication

A Free Space Optics (FSO) link consists of a transmitter and a receiver telescope which requires a continuous alignment for successful transmission of data. However due to certain factors, misalignment could occur between the transmitter and receiver telescope which later interrupts data transmissio...
