ELECTROOPTICAL DEVICE FOR CONTROLLING ELECTRICAL CIRCUIT PARAMETERS Russian patent published in 2014 - IPC G05F1/40 G02B5/00 

FIELD: physics.

SUBSTANCE: electrical circuit parameters are controlled by transmitting an optical signal through light filters to a surface of liquid crystals which, by passing through said surface and deviating by a certain angle corresponding to the wavelength, falls on a photocell which enables current of the controlled circuit to flow through a branch where said control element is located, thereby increasing or reducing the required current or voltage value, and also enabling to carry out time delay and switching methods.

EFFECT: high accuracy of controlling an electrical circuit and setting a signal time delay by transmitting and converting an optical signal.
