As an image recognition system demonstrated real-time dynamic holographic Joint Transform Correlator (JTC) based on the volume dynamic holographic environment - cadmium fluoride crystals with bistable impurity centers of gallium. Experiments showed the possibility of using this correlation to...

Certain optical means of image recognition, such as coherent optical image correlators, exhibit a serious problem of sensitivity to the scale and angular orientation of images under observation with respect to the reference image. Use of the wavelet transform processing allows one to...

I study the sensitivity of the optical wavelet correlation to changes in scale and rotation relative to recognize the image of the reference.

In this article principles of operation of a coherent optical image correlator based on a well know optical joint transform correlator are examined. Theoretical predictions and experimental data for of the optical image correlator with a holographic filter recorded on a thin holographic...

In this paper we proposed JTC with joint transform dynamical holographic filter based on CdF2:Ga crystal. JTC operation is presented at room temperature that gives correlation procedure rate at the range of 0.1–1 Hz. Experimental results demonstrate JTC ability to discriminate different kinds...

Experimental results show that dynamical hologram recorded in CdF2:Ga crystal allows one to get rather intensity correlation signal to detect it at wide dynamical range with CCD. Noise registered at the output plane of the JTC is mainly due to lens aberrations, optical elements misalignments and...
