Single-beam adaptive holographic interferometry (AHI) and small-size devices for industrial inspection

We propose a new technique of AHI which combines the high speed operation advantages of dynamic holographic interferometry and a real- time, high resolution, high stability, Denisyuk's holograms. Based on a new high sensitive phototerfractive reversible crystals group 23 doped (P and Cu) a small power CW laser was used for continuously hologram read and read-out processing. Portable wariant of a small size AHI sensor and practical demonstration of this technique are described.
