OPTICAL GENERATOR OF CHAOTIC SEQUENCES Russian patent published in 2002 - IPC

FIELD: special computer engineering, statistic modeling, design of optical means for information processing. SUBSTANCE: optical generator of chaotic sequences has source of radiation of calibrated intensity, optical splitter, electrooptical amplitude modulator, optical phase modulator and is supplemented with optical coupler having two input and three output optical branches ensuring branching of half of output optical flux into third output optical branch and its subsequent branching into two optical fluxes in first and second output optical branches, amplifier, optical integrator, optical delay element and computing transparency. Output of source of radiation of calibrated intensity is connected to input of optical splitter, which output of second branching securing branching half of output optical flux is connected to input of second input optical branching. Output of first optical branching is connected to information input of electrooptical amplitude modulator which controlling input is connected to output of first output optical branching through amplifier and photodetector connected in series. Output of amplifier is combined with input of optical generator and photodetector is coupled to output of first output optical branching and its output is connected to input of first optical branching of optical integrator. Input of second optical branching of it is connected to output of second output optical branching of optical coupler through computing transparency and optical delay element connected in series. Output of optical integrator is connected through optical phase modulator to input of first input optical branching of optical coupler. Output of third optical branching of it is output of generator. EFFECT: formation of chaotic process with specified degree of " randomness " and distribution law approximating uniform process with controllable accuracy.
