Infrared Thermography
Infrared thermography is the process of
acquisition and analysis of thermal
information from non-contact thermal imaging
devices.

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

Benefits of Thermography
• Reduce unscheduled power outages
• Detect problems quickly, without interrupting
service
• Assess priorities for corrective action
• Minimize preventive maintenance and
troubleshooting time
• Check for defective equipment while still under
manufacturer warranty
• Comply with insurance company requirements
