OPTICAL DEVICE FOR DETERMINING INPUT NUMBER OF DEVICE ON HAVING ZERO LEVEL SIGNAL Russian patent published in 2011 - IPC G06E3/00 

FIELD: physics.

SUBSTANCE: optical device for determining the input number of a device having a zero level signal has a radiation source, an n-output splitter, a linear transparency filter, electrooptical deflectors and optical coupler. The linear transparency filter can generate light flux with intensity proportional to its input number. Data inputs of the electrooptical deflectors are connected to outputs of the linear transparency filter. Control inputs of the electrooptical deflectors are inputs of the device, and their outputs are connected to corresponding inputs of the optical n-input coupler whose output is the output of the device.

EFFECT: high computational efficiency, simple design.
