(14) and the bottom layer driving software of galvanometer Y-direction motion control board (15) can convert these data to galvanometer motion control telecommunications
Number to make vibration mirror scanning motor (13) operate；
(3) laser beam that the laser emitter (9) is launched forms multiple laser by the diffraction grating (8) and projects
On the X-Y laser high-speeds scanning galvanometer (7), after the X-Y laser high-speeds scanning galvanometer (7) is reflected, while projecting multiple
Laser facula, that is, laser analog bullet to perspective plane, the X-Y laser high-speeds scanning galvanometer (7) is according to galvanometer motion control instruction
Cooperate movement, and laser analog bullet is driven to do the rectangle back and forth movement of periodic path closure；
(4) according to actual needs, the firing rate of laser analog bullet is adjusted by scanning track debugging and control card (21)；
(5) according to actual needs, the position that the tripod (2) adjusts the laser pellet injector (1) is adjusted again
Posture is so that the flight path height and angle of simulation bullet meet test needs；
(6) flight path and emission parameter of simulating bullet are calculated.
10. laser bullet analog transmissions control method according to claim 9, which is characterized in that fly to simulation bullet
Row track and emission parameter include when being calculated:
