ABSTRACT:
The invention provides a gun sight into which an aiming mark in the form of a cross is introduced. A rotatable reflector scanning an LED array directs an image of the array first towards one light transmission system and then towards another during the course of rotation. The image travelling through one system is rotated relative to the image travelling through the other system and the two images are combined. Control means are provided selectively to energize individual ones of the LED's so that the effect of combining the two images is a cross the center of which can be chosen by controlling which of the LED's is energized different times.
