Paper Abstract
It is well-known that in a hyperbola can not give two identical optical spot having the same radius except symmetrical
part. It has collimating method to decrease the divergent angle for the laser propagation, but the divergent angle cannot
be reached zero [1]. So some opinions regarded that optical spot preservation can not be realized in the transmission of
laser beam. We have suggested a method called double-lens method used for promoting the solution of such
problem [2]. However, the physical pattern used to be not very clear such as the adaptive limits; whether or not the size of
the optical spot can be arbitrarily taken; the law of the optical spot preservation versus double-lens distances etc. Since
only one hyperbola can not be realized the optical-spot preservation, let's consider more than one hyperbola that
encounter in space with different parameters, so it is possible to find out that there are some optical spots with the same
size located at different position along the transmission line and the connection of them will be achieved a continuous
flow corresponding to the propagation of the laser wave. According to this analysis, a laser beam with the certain radius
can be emitted to the artificial satellite, even back and forth; the size of the optical spot remains a constant. In this paper,
I positively say the optical spot preservation can be not only proved by mathematical derivation but realized by practice
in the laboratory. [3] It will be applied to collision avoidance [4].
