Abstract

The invention discloses a laser irradiation effect test system, comprising: a laser emitting mechanism for emitting laser beams; a laser beam adjusting mechanism arranged on one side of the laser emitting mechanism for adjusting the parameters of the emitted laser beam; The effect simulation mechanism is set on the optical path of the laser beam adjusted by the laser beam adjustment mechanism, and is used to simulate the influence of the atmosphere on the adjusted laser beam during the transmission process; the target adjustment mechanism is set on the atmospheric effect simulation mechanism far away from the laser beam. One side of the beam adjustment mechanism is used to fix the target and adjust the positional relationship between the target and the laser beam irradiated on the target; the airflow environment simulation mechanism is set on the side of the target adjustment mechanism to simulate the airflow state around the target; The radiation effect measurement mechanism is used to measure the energy of the laser beam irradiated on the target, and the damage of the target when the laser beam irradiates the target. The invention can realize repeated laser irradiation effect tests under laboratory conditions.

Description

technical field [0001] The invention belongs to the technical field of laser irradiation testing, in particular to a laser irradiation effect testing system and method. Background technique [0002] Laser equipment can emit laser beams in a directional way to irradiate the target, so that the target is destroyed or its performance is reduced. It is a new concept equipment with high damage accuracy, diverse damage modes, and low cost-effectiveness. Laser radiation effect research is one of the core technologies of laser equipment development, and the necessary means to carry out research is laser radiation effect test. In the laser irradiation effect test, the laser equipment emits a laser beam to irradiate the target, and comprehensively evaluates the radiation of the laser equipment to the target by measuring data such as laser power level, system tracking and aiming jitter, atmospheric turbulence effect, and target physical characteristics during the test. according to ef...
