In current scenario, if any person is trapped under the damaged building then the only way to identify its position is to search in the pile of concrete. This process is time consuming and chances of finding the body in short period of time are less.

What is Infrared? Infrared Detector Technologies Different Types of Imaging Qualitative vs. Quantitative • Qualitative Applications • Quantitative Applications • Many Others
Detector Technologies • Detectors are made from a wide variety of
Materials, but fundamentally work in 2 ways: • Photon Detectors • InSb / QWIP / InGaAs / MCT/ PtSi • Based on energy filling a “well” in a given time period • Variable time period • Typically cooled cameras used for R&D or demanding applications • Focal Plane Arrays (FPA’s) • VOx / ASi / • Based on energy arriving on a resistance “bridge” in a specific time period • Typically “uncooled” cameras • Majority of industrial cameras work this way
• Food Inspection • Checking meat temperature • Looking for bruises
• Medical
Imaging • Fever
detection • Fluid transfer • Diagnosis
• Semiconductor • Hot spots • Bad solder
• Telecommunications • Laser inspection

THERMOGRAPHY
Production (De-Barking Process)
Steam
• Challenge • Operators can not “see” through
the steam cloud caused by condensation in cooler air temperatures.
• Solution • IR offers another pair of eyes to
“see” through the steam into the Log Vat for proper log alignment.

THERMOGRAPHY
Quality Control (Defroster Element Integrity Check)
• Challenge • Optional features in vehicles cannot
be inspected without some type of contact. • 100% inspection is tedious and expensive.
• Solution
Unable to “see” with visible system.
• IR can be permanently mounted to
inspect these items. • IR can be used in a “non-contact” method. Broken defroster element

THERMOGRAPHY
Quality Control (Heated Seat Check)
• Challenge • Optional features in vehicles cannot
be inspected without some type of contact. • This slows production down. • 100% inspection is tedious.
• Solution • IR can be permanently mounted to
inspect these items. • IR can be used in a “non-contact” method.
