Аннотация 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 light scattering with the crystal volume. Registration system noise doesn’t affect the resulting noise level since CCD operates far from its threshold of sensitivity. To raise discrimination capability of the JTC proposed it can be added by wavelet filter that realize wavelet-transform operation. It is well known that the wavelet transform is an effective tool for feature extraction in pattern recognition.
