6. Visual vs. Night Vision vs. Thermal Imaging
• Visual
• Thermal imaging
• Night vision
• Color absorption
and reflection
• Requires some
light
Visible light image
• Amplifies small
amounts of visible
light
• Requires some
light i.e. moonlight
or LED
Near infrared “Night Vision” image
• Detects heat energy
emitted by objects
• Requires absolutely
no light
• Totally unaffected by
light sources
