Laser fusion implosion shock wave speed and shock wave waveform simultaneous diagnosis method

The invention discloses a laser fusion implosion shock wave speed and shock wave waveform simultaneous diagnosis method, which comprises a polyhedral rotating body reflector and a VISAR imaging system, and is characterized by comprising the following steps: step 1, dividing a switching reflector into N areas according to a shock wave shape change range; step 2, constructing a polyhedral rotating body reflector according to the ellipsoidal mirror equation; step 3, replacing a switching reflector with the multi-surface type rotating body reflector, acquiring probe light rays reflected by the multi-surface type rotating body reflector through shock wave probe light which is inclined at different angles at the same position by the streak camera, and correspondingly imaging in different areas of a slit of the streak camera; and 4, analyzing interference fringes formed by the slit of the streak camera to realize simultaneous diagnosis of the speed and waveform of the shock wave. The method has the beneficial effect
