Real-time display of the speckle vibration measurement with liquid-crystal
Principle and arrangment for real-time display of in-plance vibration by speckle method with the aid of liquid-crystal valve is presented. White light is used as the writing beam and He-Ne laser as the reading beam. The preliminary experimental results are given. The amplitude calculated from the real-time displayed Bessel fringes is in good agreement with the actual one.
