ABSTRACT:
A night vision module is adaptable as an input stage on a daylight viewing and aiming device for constituting a system operational during night. It comprises an infra-red imaging unit and a unit for reproducing an image of the field of view of the imaging unit on a screen for display in the input field of the daylight device which has fixed reference marks. The image reproducing unit has a generator for inlaying, in the image of the field, a plurality of marks having a predetermined position with respect to the optical axis of the module, out of the central aiming zone. The inlaid marks are so located as to be centered with respect to the fixed reference marks when the module is harmonized. The module further comprises potentiometers enabling to control the location of the image on the screen and to center the inlaid marks with respect to the reference marks.
