Electromagnetic Spectrum Notes 1) Our atmosphere receives most of its energy from the sun. This energy travels in waves from the sun called electromagnetic.

Energy Ability to do work Many different forms Conservation of energy (Law) Transformed: example: – Radiant to Thermal – Kinetic to Thermal (friction)

Thermal radiation Any object that is hot gives off light known as Thermal Radiation.  The hotter an object is, the more light it emits.  As the temperature.

FLIR OVERVIEW Forward Looking Infrared Camera Forward Looking Infrared Camera The Department currently has the ThermaCam GasFindIR model. The Department currently has the ThermaCam GasFindIR model. Without getting into the science on how the camera operates, the camera basically shows the different temperatures of objects depending on their ability to transfer, reflect and maintain heat. Without getting into the science on how the camera operates, the camera basically shows the different temperatures of objects depending on their ability to transfer, reflect and maintain heat. Camera polarity allow for either white hot or black hot images. Camera polarity allow for either white hot or black hot images.

FLIR Overview The FLIR camera sees a gas cloud because: The FLIR camera sees a gas cloud because: 1. The temperature of the gas cloud is different from the background temperature. 2. The gas cloud is moving relative to the background. (Freeze Frame) 3. The gas cloud absorbs IR energy in the wave band the camera is sensitive to.
