1.5 IMAGE INTENSIFIED NIGHT VISION VERSUS INFRARED
THERMAL VISION
Image Intensification “I
2
” works by collecting tiny amounts of light, including the lower portion of the
infrared light spectrum, that are present but may be imperceptible to our eyes, and amplifying it to the
point that we can easily observe the image.
Thermal imaging technology operates by capturing the upper portion of the infrared light spectrum, which
is emitted as heat by objects instead of simply reflected as light. Hotter objects, such as warm bodies,
emit more of this light than cooler objects, like trees or buildings.
The thermal vision device makes images from heat, not light, a feat impossible for the naked eye or
image intensified (I
2
) night vision devices. This allows you to see clearly without any visible light. People,
animals, and objects all generate or reflect heat, and are clearly seen by the thermal vision device, in
even the most adverse conditions.
Thermal is best used to detect the desired object. It is the best 24-hour imaging option.
Night vision devices provide a more natural image, wider field of view (FOV), wider operating
temperature, and longer battery life.
