In addition, this article took the isoclinic information which unwrapped already into isochromatic formula to get the correct retardation. This method might not get the form of arc-tangent because there are not output quarter-wave plates in three and six phase-stepping methods. Therefore, this paper corrected it by load-stepping method.
另外,为了使相位展开技术能顺利完成,进而得到相对的延迟量,在修正等色线包裹相位图中的不连续点时,本文使用之方法是将修正完的正确等倾线数值带入等色线公式中,此法在三场与六场中因为少掉了输出的四分之一波板,造成公式的结果使得条纹角度分布非反正切形式,因此需另外使用负载相移法来做修正。

At the same time, under the condition of small strain, firstly, the secant shear modulus was always larger than the tangent shear modulus. Secondly, when the logarithmic coordinates were applied to describe shear strain, the decrease of shear modulus with shear strain could be expressed by reversed S shape curve with two inflexion points, and through analyzing and validating, the deduced equation could perfectly reflect this characteristic. Finally, different stress paths and strain areas would lead to different attenuation trends.
而且,在小应变范围内,割线剪切模量总是大于切线剪切模量;当剪切应变采用对数坐标表示时,剪切模量随着剪切应变的增加而衰减,且衰减的规律都可以表示为带有两个拐点的反S型曲线,经分析验证本文所得公式3可以对此特性进行很好地反映;但应力路径、应变范围不同其衰减幅度不同。

We expect it will benefit the industry field to break through the optical measuring limits at present by offering some new ideas. Optical measuring research based on moire interferometry has developed for several decades. The main idea of this research is to utilize the moire effect caused by two superimposed gratings of identical or similar spatial frequency. One is the reference grating and it is a virtual grating created by a computer program in this research; The other grating is the image of grating projected on the measured surface by the DLP projector, and this grating will distort because of the different sloped profile of the surface. To superimpose the program-created grating and the captured distorted grating will derive the so-called moire effect. This research combined the basic theory of optical interferometry and moire effect to project the different phases of the projected grating fringes by the phase-shifting method and compute the principal value of arguments between -π,π. In the end, the phase unwrapping program based on discrete Fourier transform of solving PDEs is used to unwrap the phase of the measured surface, and finally the surface profile is derived by the optical measuring system.
以叠纹干涉术为基础的光学检测研究之发展早已行之有年,而在本研究中所采用的投影叠纹法(Projection moiré)之主要精神在於藉由两道空间频率相近或相同的光栅相互叠加而成的效应,其中一道为参考光栅,而本研究中的参考光栅是以程式产生可调整不同空间频率的虚拟光栅;另一道则为投影至待测物表面的光栅影像,而在起伏高度不一的待测表面上的光栅影像会受到待测物表面起伏状况不同而在观测方向产生光栅投影条纹影像的歪曲变形,将电脑产生的参考光栅与由影像撷取装置所获取投影於待测物表面的光栅影像作叠合,便会产生所谓的叠纹效应;利用基本的光学干涉理论与叠纹效应结合,本研究中以相移法来改变投影於待测表面的光栅相位,再以相移法的理论反运算出在带有待测面各点高度资讯之介於-π,π相位主幅角,再以离散傅立叶转换解偏微分方程的相位重建程式还原待测面的相位值,以得知待测面之表面轮廓。
