Paper Abstract

We realized new adaptive holographic sensor and interferometer, which allows to visualize high-resolution 3D images of diffuse reflected objects in Continue Hologram Registration Regime- CHRR. The coupled laser wave nonlinear theory was applied for optimization of hologram recording in crystals symmetry 23 and optimized experimental set up. Experimentally demonstrated dynamical holographic image sensors on doped 23 symmetry photosensitive crystals, with resolution 7900-lines/mm at 632 nm and 11641 lines/mm at 440 nm for 15 mW CW HeNe and He-Cd lasers. The results are presented for holographic visualization of Cryogenic and Ultrasonic near field images of Surgical Medical Instrument. Application of CHRR interferometer for hologram registration of moving biological object in "vivo" is illustrated.
