摘　　要：光源是动光弹试验系统非常重要的装置之一，EGB激光光源应用于动光弹试验系统，是对原来系统设备的创新和升华。EGB激光是由红激光、绿激光和蓝激光合成，既可以作为单一波长的激光光源，也能合成输出白激光光源，在动光弹试验中可以采集到的彩色的等差线，甚至可以采集黑色的零级条纹，便与分离等差线与等倾线，将极大地提高瞬态应力和应力波传播的分析研究能力。Dynamic photoelasticity method is an experimental stress analysis method, which researches the dynamic stress and the stress wave propagation. Light source is important device in dynamic photoelastic experiment system, and the RGB laser light source applied in dynamic photoelastic experiment system is innovative and evaluative. RGB laser is synthesized by red laser, green laser and blue laser, either as a single wavelength laser light source, also as synthesized white laser light source. RGB laser as a light source for dynamic photoelastic experiment system, the colored isochromatic can be captured in dynamic photoelastic experiment, and even the black zero-level stripe can be collected, and the isoclines can also be collected. It will vastly improve the analysis and study power of transient stress and stress wave propagation.
