【摘要】 对高速分幅照相的传统照明技术进行了改进,发展了带背景的前照明摄影技术。用激发炸药加氩气袋作为前照明光源,在被照相物体的背后悬挂屏幕作为背景,利用前照明光源在背景屏幕上的漫反射光作为后照明,可以获取边界清晰前照明分幅照相照片。应用此技术对爆轰加载下金属柱壳的膨胀断裂过程进行拍摄,获取了柱壳前表面与边界均很清晰的动态实验照片。更多还原

【Abstract】 The illumination technology of high-speed photograph has been developed. The frontal illuminations with backdrop have been applied in high-speed photograph. The frontal illuminations are made up with two argon bags inspired by explosive. A backdrop is set behind setup,which diffuse reflect light for behind illumination. So the boundaries of setup (shell) are distinct. Applying this technology to film the process of expanding metal shells by detonation driving,the distinct dynamic pictures have been obtained.更多还原
