Abstract

A new holographic technique to measure the size and velocities of fine particles has been developed. The two lasers of different wave length are set up in the same optical axis, and fired at an interval of few micro seconds. The two output beams with inline holographic information of the object particles are separated by a beam splitting cube and two interference filters, then the holograms of moving particle system at the different instants are recorded on the two films separately. These two holograms are super-imposed each other and the moving distances of particles are measured microscopically. This new technique is applied to observe the distribution of particle velocities induced by a shock wave.
