Paper Abstract

The high speed photography & photonics have been used widely in the field of mechanics in China such as the study of shock wave, exit trajectory, armor-penetration, shock tube wind tunnel, propagation of stress wave, crack expansion, mechanical properties of material under impulsive load, interaction of laser with target, exploding wire, biotrajectory, explosion welding, blasting engineering and other applications in industry. Some techniques such as the dynamic speckl, dynamic morie, X-ray photography, dynamic photoelasticity, high speed schlieren, high speed interferography, and stroboscopic light source etc. have been used. Several instruments of HSPP used in mechanical research such as the stroboscopic Ar laser source with frequency of 5kc, stroboscopic He-Ne laser source with frequency of 20kc, double mirror interferometer with aperture of 150mm in dia., synchrolized pulsed He-Ne laser, auto-following synchronizer, 1000kv pulsed X-ray generator and its con-troller for four sets and the multi-spark high apped camera have been researched and developed. The ordinary type of the rotating mirror, stand-by and prism compensation high speed cameras, schlieren and Strobokin are also used widely. Many application pictures are also presented in this paper.
