FIELD: physics. ^ SUBSTANCE: invention relates to devices for displaying information on a windscreen and can be used in aircraft. The proposed device consists of semitransparent reflector, dual-channel collimator, display and mechanical collimator, rigidly fixed in the focal planes of the collimator channels, collapsible diaphragm, which is fixed in the operation and non-operation positions, the centre of which is on the optical axis of the collimator. ^ EFFECT: elimination of the need for use of supplementary external devices for referencing images to the coordinate system of an airplane and for shortening evaluation time of the given accuracy. ^ 2 dwg |
