Abstract: |
In this paper, a novel method of laser beam deflecting is introduced to improve the spatial resolution of an acoustic-optic
deflector (AOD). We use double AOD (DAOD) to control laser beam. Compared with single AOD, the double AOD can improve speed
and precision of target tracking and pointing significantly. Finally, a method of calculating the static and dynamic number
of resolvable poins (NRP) is and it is supported by the experimental data excellently. |
