A method and apparatus for highlighting returns from optically augmented targets includes in one embodiment a receiver, a viewing device coupled to the receiver and first and second illuminators. The first illuminator is arranged on axis with the receiver and the second illuminator is placed off-axis therefrom. Means are provided for switching on alternately the illuminators such that returns of the first illuminator through retroreflection from high quality optical targets will enter the receiver, while retroreflection returns of the off-axis illuminator will not enter the receiver; therefore the retroreflected returns from high quality optical targets will appear to flicker when seen on the viewing device and thus be highlighted above the rest of the scene.
