Abstract

PURPOSE:To enable observation in real time by storing the observation data when compressive force is exerted and tensile force is exerted and subtracting the data. CONSTITUTION:The IR rays corresponding to the compressive stress are generated from a measuring object 2 when the compressive force is exerted to the measuring object 2 by a stressing device 3. The IR rays are detected by an IR camera 1 and are supplied through an A/D converter 5 to a frame memory 6 by which said rays are stored. Similarly, the data with respect to the tensile stress are stored in a frame memory 10 where the tensile force in extended to the object 2 by the device 3. The outputs of the frame memories 6, 10 are subtracted in a subtractor 11 and are integrated further in a integrator 12. The integrated signal is subjected to a processing for an image display in an image display processor 13 and is supplied to a monitor 14. The output of the integrator 12 is recorded on a hard disk 7.
