  This thesis presents the thermographic studies via FEM simulation through three different kinds of heating methods (lock-in, pulse and step). Under investigating the relationship between thermographic results under different heating frequencies and heat fluxes, the most effective heating time and temperature are found. It is also found that the lower the heating frequency is, the easier the deeper defects of thin composite material can be identified. Simulation result also shows that it is easier to detect deeper defect by using lock-in thermographic method rather than by using pulse or step heating thermographic methods.
