Effect of laser setup position relative to trajectory on dynamic heating

According to the incidence angular factor of the laser beam, the locations of the laser setup above the ground are classified. The methods of geometrical analysis and numerical simulation are used. It is indicated that when a focused laser beam heats a flying cylinder, for the sake of the best heating effect, as to achieve enough heating power level and energy level at the same time, the trajectory point when the laser beam can irradiate the cylinder perpendicularly should be selected as the heating center, the effective work time of the laser should be regarded as the heating time range, and the laser setup should be placed at a proper distance from the cylinder at the very trajectory point. It is found that the problem of effect of relative position between laser setup and trajectory on
