OPTICO-ELECTRON DEVICE FOR VISUALIZATION OF IMAGE Russian patent published in 1994 - IPC

FIELD: mining industry. SUBSTANCE: optico-electron device has catadioptric lens 1, electron-optical converter 4, eye-piece 7, pentaprism 8, dichroic mirror 9 which is first day observation channel, lens 16 ensuring observation of space behind operator. Two supplementary lenses 10 and 11 and two rotary dichroic mirrors 12 and 13 corresponding to them provide for observation from above and from beneath (or sides) with reference to device, two rotary flat mirrors 19 and 20 and dichroic mirror 9 secure visual range of object in front and in rear as well as from above and beneath (or from sides) of device right in day time with enhanced level of illuminance. EFFECT: provision for visualization of objects located not only in front but in rear, above and beneath (or on sides) of device which means that field of vision of given device increases four-fold as compared with prototype. 1 dwg
