The laser transmission characteristics affected in the complex channel environment,
which limits the performance of laser equipment and engineering application severely. The
article aim at the influence of laser transmission in atmospheric and seawater channels,
summarizes the foreign researching work of the simulation and comprehensive test
regarding to the laser transmission characteristics in complex environment. And researched
the theory of atmospheric turbulence effect, water attenuation features, and put forward
the corresponding theoretical model. And researched the simulate technology of
atmospheric channel and sea water channel, put forward the analog device plan, adopt the
similar theory of flowing to simulate the atmosphere turbulence .When the flowing has the
same condition of geometric limits including the same Reynolds, they must be similar to
each other in the motivation despite of the difference in the size, speed, and intrinsic quality.
On this basis, set up a device for complex channel simulation and comprehensive testing, the
overall design of the structure of the device, Hot and Cold Air Convection Simulation of
Atmospheric Turbulence, mainly consists of cell body, heating systems, cooling systems,
automatic control system. he simulator provides platform and method for the basic research
of laser transmission characteristics in the domestic.
