现在假设有一定的线性度,就可以说磁化和旋转强度是可以测量的。Y分量由饱和场归一化测量。m磁化分量实际上是百分之百的,m分量被确定为0。为了实现某种形式的纵向和横向磁化,矢量磁场的复杂性必须降低。偏振器在这一点上尽可能小心地对准。测量进行到一点的差异,在滞后回路达到零。在这一点上,偏振器的位置应用于测量x分量。还有其他重要的方法来了解磁矢量信息从Moke测量。例如,研究人员通过使用纵向MOKE测量来评估如何收集矢量信息。入射光的偏振是通过相对于样品方向的旋转来计算的。

这是在应用的字段保持不变的情况下完成的。然而,这种方法也缺乏,因为要收集来了解横向分量的定量信息并没有很好地定义。因此,这就进入了分析的下一个阶段,研究人员利用矢量磁法进行光弹性调制。这样做的唯一目的是完善第一种方法中没有考虑到的技术。利用光弹性调制器PEM实现了光弹性调制。PEM基本上是一种光学设备,用于调制来自光源的偏振光。光弹性调制器使用的基础是光弹性效应。PEM最初是为了理解双折射而开发的。光弹性调制器的基本工作原理是将光弹性调制器作为谐振器件。

振荡频率由所使用的光学元件和换能器组件决定。通常,换能器的装配也基于谐振频率。换能器将根据安装中使用的光学元件的要求调谐到共振频率。通常考虑的光学元件特性有速度、长度、声速、基本长尺寸等。通常送入换能器的电流在拉伸和压缩过程中会引起光学元件的振动,因此对换能器是有帮助的。这里的贫困已经扩大了。透明材料由于拉伸和压缩作用而发生变化。这种形式的共振特性意味着光学元件的双须性将被调制以满足更大的振幅。它也会受到频率的限制。PEM操作通常仅限于单个频率。

Now assuming some amount of linearity, it could be said that magnetization and rotation intensity could be measured. Y component is measured as normalized by the saturation field. The m magnetization component is actually 100 percent, and the m component is identified to be 0. In order for there to be some form of longitudinal and transverse magnetization, there has to be less complications of the vector MOKE. Polarizer is aligned as carefully as possible at this point.

The measurement is done to the point the differences in hysterises loop reaches zero. It is at this point that the polarizer position is applied in measuring x component. There are significant other methods too for understanding the magnetic vector information from Moke measurement. For instance, researchers assess how vectorial information is collected by making use of longitudinal MOKE measurements. The polarization of incident light is calculated by means of rotation with respect to the orientation of the sample.

This is done while the applied field remains unchanged. However, this method is lacking too, as the quantitative information that is to be collected to understand the transverse component is not that well defined. Therefore, this brings things to the next stage of analysis where researchers made use of a vector magnetometry as applied in the case of photoelastic modulation. This was done with the sole purpose of perfecting the technique that is not considered in the first method.

A photo elastic modulation is done using the Photo elastic modulator PEM. The PEM is basically an optical device that is useful for the purpose of modulating polarized light from a light source. The basics behind the use of the photo-elastic modulator is that of the photo elastic effect. PEM was originally developed for the purpose of understanding birefringence. In the basic principle of its working, the photo elastic modulator is seen to act as a resonant device.

The oscillation frequency is determined by optical element and the transducer assembly that is used. Usually the transducer assembly is based on resonance frequency as well. The transducer would be tuned into the resonance frequency as required by optical element used in the setup. Optical element characteristics that are usually considered are that of speed, length, speed of sound, the elemental long dimensions etc.

Usually a current sent into transducer would be helpful as it results in the vibration of optical elements in stretching and compressing. The bifringence is stretched here.The transparent material bifriengence is changed because of the stretching and the compressing actions. This form of a resonant character would mean that the optical element bifringence would be modulated to meet much larger amplitudes. It would also be limited to frequency. PEM operations mostly are limited to a single frequency only.
