REMOTE OBJECT OBSERVATION SYSTEM Russian patent published in 1998 - IPC

FIELD: search and identification of very small and remote objects in wide field of vision. SUBSTANCE: system designed for observing objects as small as down to 0.2 m at distance up to 10 km has high-resolution, long-focus, wide-angle lens, at least one image receiver mounted for displacement within field of vision of long-focus, wide-angle lens and along its optical axis, finder with short-focus, wide-angle lens and image receiver, long-focus lens and finder displacement gear, unit for matching object image location in finder field of vision and receiver location in field of vision of long-focus lens. Placed in image plane of long-focus lens is reflecting screen combined with image receiver and mounted for displacement along optical axis of long-focus lens and within its focal plane. Matching unit is made in the form of mirror arranged between long-focus lens and screen for moving along optical axis of long-focus lens and at angle α to its optical axis, where 0 < α < 180^°; finder is placed along radiation path reflected from mirror for matching its image receiver with screen. EFFECT: enlarged field of vision, improved precision of aiming at small-size objects. 4 cl, 2 dwg
