BINOCULARS

FIELD: optical instruments. SUBSTANCE: invention is related to optical instrumentation engineering and is coupled to stabilization of optical image of observed objects in optical instruments operating on mobile base and designed for formation of telescopic observation system of binoculars type. Proposed binoculars with built-in stabilization system has case with two telescopic systems mounted on it. Each system includes lens, inversion optical system image stabilization system which incorporates gyrotachometer fixed in case and electrically coupled to proper amplifiers and drives of mobile optical elements anchored in elastic suspensions and power supply source. Mobile optical elements are fabricated in the form of pair of mirrors installed in series in ray path and are so placed that planes having incident and reflected rays and normal to reflecting surface of each of mirrors are mutually perpendicular, i.e. mobile mirrors form analog of known prism. Suspension axis of first mirror in ray is parallel to one of sensitivity axes of gyrotachometer and suspension axis of second mobile mirror is perpendicular to plane in which mutually perpendicular sensitivity axes of gyrotachometer are located. Main point of invention consists in that sensitivity axes of gyrotachometer are so oriented with reference to suspension axes of mirrors that summary movement of object viewed through binoculars presents sum of mutually perpendicular movements with equal coefficients of optical observation, namely 1:2 relative to mirrors along both directions. proposed binoculars with built-in stabilization system of image makes it possible to conduct visual-optical observation from mobile bases, for instance, from helicopter, automobile or ship. EFFECT: increased quality of visual-optical observation in presence of angular oscillations of case of binocular due to tremor of hands, for instance, when observation time is not limited. Изобретение относится к оптическому приборостроению, связано со стабилизацией оптического изображения наблюдаемых объектов в оптических приборах, работающих на подвижном основании, и предназначено для создания телескопических наблюдательных систем типа бинокль. Для повышения качества визуально-оптического наблюдения при наличии внешних угловых колебаний корпуса бинокля, например, вследствии тремора рук, при неограниченном времени наблюдения, предлагается бинокль со встроенной в него системой стабилизации, содержащий корпус с установленными в нем двумя телес
