Design and implementation of a miniaturized beam emitting and tracking system

摘要

Aiming at tracking and attacking low altitude, slow and small targets with high power laser, a miniaturized high power laser beam emitting and tracking aiming system is designed to meet the requirements of compact type. In the beam emitting part, the single coude mirror is used to realize the waveguide system of laser beam in pitch direction. The structure is compact, which meets the requirements of miniaturization and reduces the difficulty of realization. In the pointing and tracking part, the tracking dynamic performance is improved, based on the compound-axis tracking strategy and combined with the man in the loop dynamic correction of the coarse tracking residual. The stability of the optical axis of the single coude mirror is better than 5μrad. The field test results show that the tracking accuracy of the system is 6 μrad for balloon and 9μrad for small quad-rotor unmanned aerial vehicle, which verifies the feasibility of the design of beam emitting and tracking system.
