As warfare becomes more asymmetric, civilians and other non-combatants become a larger percentage of the casualties, along with unintended property damage. The military, of course, hopes to avoid these types of casualties and destruction. With advancing technologies that enable more precision from their weapons, they also need better pointing and targeting capabilities, while remaining covert. Improved targeting technologies that allow detection and identification at longer standoff distances from the designators also are needed. For instance, lasers are excellent at precision pointing, but it is important that others be able to covertly image the scene as well.

To address these targeting challenges, the military has deployed lasers that allow them to not only deployed lasers that allow them to not only designate the target where munitions should hit, but to use these same lasers to measure the distance to the target, illuminate the surrounding area, or point out to others something of interest. Visualizing where the lasers are pointing, tracking moving targets, and minimizing collateral damage require imaging systems that see the active lasers used in the field. Room-temperature indium gallium arsenide (InGaAs) cameras give users this capability in day or night conditions.
