A correction method for beam hardening, involving simple operations of the original polychrornatic projection sinogram, was presented based on the analysis of three physics properties implied by beam hardening. Its correction principle was deduced mathematically. A noise reduction method was proposed to suppress the noise enlarged by the harden correction by processing the high-frequency and the low-frequency components in the projection sinogram respectively.

This study used the pick-up head from the commercial DVD-ROM as the basis for optical path, and drilled a 2mm hole on the focusing object lens. After combined with the design of a beams plitter, the laser beam source of the two DVD formed two in-line laser beams. One laser beam passed through the undrilled part, and focused on the surface of the object to be tested, in order to measure the displacement variance of the surface.

The experimental results show that: the failure mode of strengthened beam at elevated temperature can be classified as flexure failure mode or flexure-shear failure mode, and the failure mode of strengthened beam at high temperature may be different from that at room temperature; and although the load supported by the strengthened specimen is larger than that supported by the unstrengthened specimen, the fire resistance of the strengthened specimen is still larger than that of the unstrengthened specimen, due to the influence of fire insulation.
