A digital representation algorithm for long distance transmission laser spot energy intensity distribution

An algorithm is designed to realize the digital representation of long distance transmission laser spot energy intensity distribution, due to the current situation that the energy intensity of long distance transmission laser spots cannot be accurately represented in the laser system. A definite number is obtained by image processing and program calculation of a laser spot. The simulated laser spots are calculated and contrasted to verify the universality and applicability of the algorithm. The calculation results show that the spots size have negative impact on the representation results. Using this algorithm, the adjustment criterion of the long distance transmission laser spots in the laser system can be set more conveniently.
