The invention relates to optical instruments, more specifically to electronic diffraction diaphragms, controllable light-adjusting elements and optical filters for objectives, cameras and other optical devices. A device has been developed for adjusting optical devices and changing the intensity, direction and concentration of light rays in optical instruments by creating, in real time or a specified time, variable diffraction stencil patterns (plane-parallel and perpendicular bands, concentric circles and other shapes) on an element of an electronic diaphragm. The electronic diffraction diaphragm device can operate both in a dynamic and in a static operation mode of the element. A device of this kind enhances the capabilities of other optical instruments and cameras and improves or changes the characteristics thereof.
