Description: matlab模拟两束平面波干涉
（1）光源非单色性的影响
实际光源不是绝对的单色，包含一定的光谱宽度△λ。△λ范围内的每一种波长的光都生成各自一组干涉条纹，除零干涉级外，相互间均有位移，使条纹对比度下降。
能产生干涉条纹的最大光程差称为相干长度。与光源的光谱宽度成反比。光源的光谱宽度越小，就能在更大的光程差下观察到干涉条纹。
（2）两相干光波振幅比的影响
振幅相差越大，对比度越小。若两相干光波的振幅相差很大，两相干光波造成的强度实际上与其中较大强度的一个光波单独产生的强度没有多大区别，这时干涉场几乎为一片均匀照度，看不出干涉条纹。
-matlab simulation of plane wave two-beam interference (1) the impact of non-monochromatic light source is not absolute actual color, it contains a certain spectral width △ λ. Each of the light wavelength in the range of △ λ generates a respective set of interference fringes, in addition to the zero level outside interference, are mutually displaced so that fringe contrast decreases. It can produce interference fringes maximum optical path difference is called the coherence length. And inversely proportional to the spectral width of the light source. The smaller the spectral width of the light source, the greater can be observed under the optical path difference of interference fringes. (2) Effect of coherent light wave amplitude ratio of the two amplitudes greater the difference, the lower the contrast. If the amplitude of the two coherent lightwave vary widely, due to the strength of two coherent light intensity which is actually a large light intensity alone does not produce much dif

Description: 下面给出了48项泽尼克多项式，外加一项常数项。需要注意的是，读者并不需要严格按照下文所示的顺序排列这些泽尼克项，实际上在不同的应用和机构会采用不同的排列顺序。
表中的#0项是个常数或者说是平移项（piston term），这一项的系数也代表了平均光程差；而#1和#2项分别是x和y方向的倾斜项（tilt terms），#3代表了聚焦，因此，#1到#3项代表了波前的高斯或者近轴特性；#4和#5项代表了像散和离焦，#6和#7项代表彗差和倾斜，而#8项代表了3级像差和离焦，也就是说#4到#8项为3级相差项；同样地，#9到#15项代表了5级像差，而#16到#24项代表了7级像差，#25到#35项代表了9级像差，#36到#48项代表了11级像差。(Here are 48 Zernike polynomials, plus a constant term. It is important to note that the reader does not need to strictly arrange the Zernike entries in the order shown below, but in fact different orders of arrangement are applied to different applications and institutions.
Table #0 is a constant or a shift (piston term), a coefficient of this term also represents the average optical path difference; while #1 and #2 are inclined X and Y direction (tilt terms), #3 represents the focus, therefore, #1 to #3 on behalf of the wavefront. Gauss or paraxial properties; #4 and #5 represent the astigmatism and defocus, #6 and #7 represent coma and tilt, and #8 represents the 3 order aberration and defocus, that is to say #4 to #8 is 3 level difference; similarly, #9 to #15 on behalf of the 5 order aberration #16 and #24, to represent the 7 level #25 to #35 aberration, on behalf of the 9 #36 to #48 aberration, on behalf of the 11 order aberration.)
