Abstract
A new conception of adaptive microsensor based on single beam dynamic holographic interferometry SBDHI is presented. A practically unlimited number of read and readout hologram cycles without application of external electric field using supersmall 0.12 micrometer dynamic holographic grating in double-doped titanium sillenite photorefractive crystal created by low power He-Ne or diode laser leads to invention of a portable, high stability, low-cost device for fast optical measurements on-line. A pen-size real-time SBDHI for stress measurements in this films and vibration mode visualization in situ has been constructed.
