OPTOELECTRONIC DEPHASING APPARATUS Russian patent published in 2010 - IPC G06E3/00 

FIELD: physics.

SUBSTANCE: device has two series-arranged Fourier transformation systems and an operational spatial filter, which form an optical indefinite integrator, a coherent radiation source, whose output is connected through a linear transparency filter to inputs of corresponding optical Y-splitters, whose second outputs are connected to corresponding inputs of the optical indefinite integrator, and first outputs of the optical Y-splitters are connected through series-connected optical indefinite integrator and second linear transparency filter to the input of an optical phase modulator, whose output is connected through an optical n-output splitter to first inputs of optical Y-couplers, outputs of the optical indefinite integrator are connected to second inputs of optical Y-couplers, whose outputs are connected through series-connected photodetectors and null indicators to inputs of an encoding device, whose outputs are the output of the device.

EFFECT: high computational efficiency of the dephasing process.
