The higher rate of the success for the holographic recording and the higher contrast for the interference fringes have been obtained by this system.

In this article we have theoretically and experimentally discussed how the deformation of a stressed thin plate is measured by real-time holography with bso-crystal and automatic hologram calculation.

A real time holographic testing method of transparent objects by using the interference pattern formed by the reconstruction of the reference wave and the original reference wave is introduced.
