專利摘要(中)
An apparatus for quantifying unknown stress and residual stress of a material to be tested, the material being a birefringent or temporary birefringent material, which includes a light source, a polarizer in front of the light source for converting a light beam from the light source into a beam with linear polarization, a first quarter-wave plate in front of the polarizer for generating circular polarization, a standard material, a second quarter-wave plate, an analyzer, a loading unit, a spectrometer for obtaining transmissivity spectrum of the standard material under the wavelength of the light source and a detecting module connected to the spectrometer to have the transmissivity spectrum of the material to be tested and consequently a stress quantifying formula for the standard material.
