Laser Communication and Imaging

Laser communication is wireless connections through the atmosphere. It is now able to send information at data rates up to several Gbps and at a distance of thousands of kilometers apart.

The information is sent to the light modulator which is connected with laser. The modulator processes the information on a laser by adjusting amplitude, frequency or phase. Then the information is transmitted by optical antenna. At the receiving end, the oscillator and signal are mixed and then transformed into the original information by the photoelectric balance detector and loop filter, after amplification and demodulation.

Laser communication has the advantages of small transmission loss, long transmission distance, high communication quality, large communication capacity, strong confidentiality and light structure. It is mainly used for ground communication, global communication and interstellar communication.

variety of materials, including marble, wood, glass, plastics, painted metals, textiles, anodized aluminum and more. The imaging system has the advantages of high resolution and ultra long range imaging. It can also overcome the atmospheric turbulence.
