What does CALI mean army acronym?

Answer 1

Covert Action Laser Illuminator - a feature of electro-optical and infrared (EO/IR) sensors

The EO provides day capability, IR day and night, but EO has better range capability

Lasers are used on the modern battlefield in many applications, from detecting the range of an object to designating a target for another weapon system to attack. Many military laser systems are boresighted to a visible or infrared imager center crosshair (think of that famous red laser dot you see on a target in an action movie when a sniper is getting ready to shoot). The most common battlefield lasers operate at 850 nm, 1060 nm, and approximately 1500 nm. The first two laser types are visible to current night vision goggles. The 1550 nm laser, a modern eye-safe wavelength device, is not visible with current night vision technology. 1550 nm is within the short wave infrared (SWIR) region, and is therefore considered covert, invisible to opposing forces. Covert to enemies, but highly visible to troops equipped with SWIR imaging devices, such lasers are increasingly important on the battlefield.
