Thermographic measurement techniques15
3. Measure the radiation intensity (= apparent temperature) from the reflecting source
using the following settings:
• Emissivity: 1.0
• D
obj
: 0
You can measure the radiation intensity using one of the following two methods:
Figure 15.3 1 = Reflection source
NOTE
Using a thermocouple to measure reflected apparent temperature is not recommended for two impor-
tant reasons:
• A thermocouple does not measure radiation intensity
• A thermocouple requires a very good thermal contact to the surface, usually by gluing and covering
the sensor by a thermal isolator.
15.2.1.1.2 Method 2: Reflector method
Follow this procedure:
1. Crumble up a large piece of aluminum foil.
2. Uncrumble the aluminum foil and attach it to a piece of cardboard of the same size.
3. Put the piece of cardboard in front of the object you want to measure. Make sure that
the side with aluminum foil points to the camera.
4. Set the emissivity to 1.0.
5. Measure the apparent temperature of the aluminum foil and write it down.
