A relatively inexpensive system is provided for detecting and visually indicating the relative location of the impact on a target of an invisible infrared laser beam emitted from a small arms transmitter (SAT) mounted on a combat rifle. A plurality of red LEDs are mounted on a planar PCB that serves as the target and are arranged along X and Y axes corresponding to azimuth and elevation. A plurality of photo-diodes are mounted on the PCB for generating output signals when struck by the laser beam. The photo-diodes are clustered around the intersection of the X and Y axes. A circuit mounted on a reverse side of the PCB is connected to the plurality of photo-diodes for receiving their output signals. The circuit energizes one or more of the red LEDs to provide a pattern of illumination of the LEDs that represents azimuth and elevation deviation of the laser hit from the intersection of the axes when the SAT is fired with the intersection of the axes in the iron sights of the rifle. The LEDs and photo-diodes are spatially arranged on the PCB to provide an effective magnification of a variation in azimuth and elevation of the location of the impact of the laser beam relative to the intersection of the axes. The circuit also increases the duration of the illumination of the LEDs compared to short duration laser pulses to increase visibility to the soldier. A pair of laser diodes can be mounted on the PCB so that visible red light beams emitted therefrom will criss-cross at the appropriate distance and overlap on the soldier's chest. This tells the soldier to fire the SAT-equipped rifle at the target at this location.
