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. |

Laser imaging: Illuminate the target with
the three frequency shift laser beam to produce
the moving interference fringes on the surface,
then receive the echo with energy detector
and demodulate echo to get the
the Fourier amplitude and phase spectrum of
target on the surface. Finally, eliminate the
atmospheric jitter by closure phase
and reconstruct the target image by the Fourier
inversion.
Our precision manufactured lasers and laser systems deliver the highest possible laser graphic
imaging performance on a wide
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. |
