A comparison of raw and post treated films for longitudinal and transversal sample is presented in Figure4

a) Infrared film frame with the longitudinal raw surface visible at mirror level and the edge of the specimen above the rollers ( = 69MPa)

b) temperature amplitude field for longitudinal configuration determined by the lock-in method

c) Infrared film frame with the transverse raw surface visible at mirror level and the edge of the specimen above the rollers ( = 130MPa)

d) temperature amplitude field for transverse configuration determined by the lock-in method
