Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0028] like figure 1 As shown, a digital laser explosion loaded dynamic photoelastic experiment system includes a laser 1, a beam expander 2, a front convex lens 3, a polarizer 4, a left 1 / 4 wave plate 5, a right 1 / 4 wave plate 6, a detector Polarizer 7, rear convex lens 8, explosive loading device 11, detonator 14, digital high-speed camera 9 and computer 10.
[0029] Wherein, the output end of the laser 1 corresponds to the beam expander 2 , and the beam expander 2 is located between the laser 1 and the front convex lens 3 . The front convex lens 3 in the field lens combination is responsible for converting the surface beam emitted by the beam expander 2 into a parallel beam, and then converges and transmits it through the rear convex lens 8 . Between the front and rear convex lenses 3 and 8, a polarizer 4, a left 1 / 4 wave plate 5, a right 1 / 4 wave plate 6, and an...
