Abstract

The invention proposes a large dynamic energy infrared target simulation system. The system is composed of a radiation source module, an optical system, a control module and supporting devices. The radiation source module includes a black body radiation source, a black body controller, a condenser lens, a light barrier, an attenuation film group and a light barrier group. The attenuator group includes attenuator A and attenuator B. The diaphragm group includes diaphragm A and diaphragm B. The optical system includes a relay optical lens and a collimating optical lens. The control module includes industrial computer (with reflective memory card and motion control card), I/O card, motor driver, servo motor, control cable and control software. The control module can control the change of the shape, size and energy of the target. The spectral characteristics of the radiation source are adjusted by adjusting the temperature of the black body through the black body controller.
