1. AGENDA… Introduction to IR Brad Risser Camera Operation / Post Analysis Capabilities Jim Hungerford

2.  IR is generated by the vibration of electrically charged particles  IR travels through space at the speed of light  The difference between light and IR is wavelength Infrared Radiation…  IR is emitted by all objects  IR radiation is minimal at low temperatures  IR radiation increases with temperature IR Theory

3. 2 Types of Analysis Qualitative – Comparative analysis IR Theory

4. Qualitative… Which is Hotter? IR Theory

5. 2 Types of Analysis Qualitative Qualitative – Comparative analysis IR TheoryQuantitative – True temperature measurement

7. Why does Infrared work for Research & Development? Non Contact Temperature Measurement (no thermal couples, non-destructive means of testing) Quick / Easy to Interpret Results (more meaningful than data) Raw Data Available Can Resolve Small Targets (12 Microns) and small temperature changes (<2 degrees C) Dynamic or Still Digital Acquisition Valuable Historic Reference

8. Loose connections, poor contact, or shorts can result in hot spots. PCB Inspection Known Good One Fault Five Faults

9. Acquisition and Analysis Static Image Analysis Full analysis capability Static Image Analysis Full analysis capability Real Time Analysis Time versus temperature Image subtraction Real Time Analysis Time versus temperature Image subtraction
