Real-Time Holographic Interferometry With Pulsed Laser

We could perform real-time holographic interferometry with Q-switched ruby laser. When real-time holographic interferometry is done using pulsed laser light, we can freeze high speed events and observe their changes of states as interference fringes, because Q-switced laser pulse has an extremely short pulse duration and high intensity. Further we could get a double-pulse and observe serial two images of an event as real-time holographic interfer-ence fringes using a high speed streak camera to separate them.
