A directional laser emitting equipment was designed and manufactured based on Coude optical system which can align the axis of the laser emitting with the center of the field of view of the optical track-pointing subsystem in one structure,and the control program of the two-dimension rotating platform was developed,which can control the laser to emit to any direction in a certain airspace. With the directional laser emitting equipment and the control program,experiments about optical track-pointing and laser attacking at balloon targets were accomplished in lab.
