Along with the rapid development of construction engineering,infrared thermography testinghas been being increasingly applied to quality check for engineering projects.

In this paper, according to study the familiar impacting source,by the technique of falling body impact experiment and infrared thermal imaging testing,the typical low-energy impact damages of aircraft composite ma- terial were simulated and studied.

SLXL-3 infrared gas detection logging unit;

In this paper,temperature fields of substrates and coatings taken by thermal imager when the coating damage happened were comparatively studied to find the occurrence area of damage,and then the temperature curve through the damage area was obtained for the further discussion of temperature fluctuation in this area.

The situation and principle of thermal imager were introduced,and its application in building energy efficiency testing was discussed.

The development of radiation thermometry and the thermal imager has been reviewed and the problems were analyzed from technique degree.

Accurate measuring temperature with infrared thermal imager;

Theoretical analysis on the technics of temperature measurement precision with infrared thermal imager;

In the process of drying soft capsules,an infrared thermal imager was applied to measure the surface temperature distribution.
