Laser fusion shock wave velocity measurement method and shock wave velocity interferometer

The invention relates to a shock wave velocity measuring method and measuring device, in particular to a laser fusion shock wave velocity measuring method and a shock wave velocity interferometer. The technical problem that only local impact compression information of a fuel ball can be obtained due to the fact that an existing velocity interferometer is too large in size and limited in installation position is solved. The measurement method comprises the following steps: focusing probe light emitted by an illumination optical fiber on a target spot to be measured; a light receiving lens is adopted to collect the generated Doppler frequency shift light, and the Doppler frequency shift light is collimated into parallel light beams; the parallel light beams are divided into two paths and enter two interferometers in sequence; enabling coherent signals output by the two interferometers to perform time division multiplexing on one streak camera; two paths of coherent signals are measured through the streak camera
