ELECTRONIC DIFFRACTION DIAPHRAGM Russian patent published in 2021 - IPC G03B9/02 G02F1/01 G02B27/42 

FIELD: optics.

SUBSTANCE: invention relates to optical instrument-making and concerns an electronically controlled diffraction-diaphragm element (ECDDE). ECDDE contains housing of device, in which there is control unit on integrated circuit, system of contacts with a light-guiding electronic element made with possibility of partial or complete darkening, change of colour, as well as creation of deflection and reflection on the specified areas of the element by means of electronic control.

EFFECT: technical result consists in possibility of combining in one device functions of electronic controlled diaphragm, light filter and optical corrector and enabling change of optical properties of device in real or preset time.
