The model of fiber-optic Fabry-Perot interferometer was established when ideal or unideal optical source was applied. Through simulating interferometric signal by computer under the condition of nonmonochromatic light, the symmetry of fringes deteriorated, the fluctuating domain of fringes became small as the ratio of cavity length to coherence length increasing.

推导了光源在理想情况和非理想情况下的光纤Fabry-Perot干涉模型，通过计算机模拟了干涉信号，指出在非单色光源下，干涉条纹失去周期性，随着腔长相干长度比增加干涉条纹的变化幅度减小，最后演化成一条直线，条纹的可见度也慢慢趋近于零。

Then, we analyzed the the principles of the white device. Besides, we make this kind of white OLED to match with LCD screen. The maximal active area achieved 3cm×3cm. The average brightness of the device reached 1300cd/m^2 at 10V, and the uniformization of brightness was 90%. So it can be concluded that the white OLED well satisfied the need for LCD-backlighting.

Restaurants, the most important is the light in table above shall be prior to table size and shape to choose lamps, as in the great circle of the upper plate with long-hidden under a supply auxiliary light source or in the long dinner table together with two sticks of long-term chandelier will make the atmosphere more restaurant family love.

餐厅里，最重要的光源显然应在餐桌上方，应事先掌握餐桌的形状和尺寸来选择灯具，如在大圆餐桌的上方装一圈隐蔽式下射灯作辅助光源或在长餐桌上并列装二支长线吊灯，都会使餐厅的氛围更加温馨可人。

However, unlike the light source relative to the rest of the observer to see is the colorless astigmatism, and the light source relative motion of the observer to see is the red-shift light ( achromatous astigmatism occurs redshift of red-shift light ); Although the different inertial reference frame of the observer can see the speed of light, after the Lorentz transformation is the same as after c; but a different observer are exposed to the light energy is not the same achromatous (astigmatism energy and achromatous astigmatism occurs after the red-shift of red-shift of the light energy is out of the same ).

但是，与光源相对静止的观察者看到的是无色散光，而与光源相对运动的观察者看到的是红移光（无色散光发生红移后的红移光）；虽然，不同惯性参照系的观察者看到的光速，经过洛伦兹坐标变换后都一样为c；可是不同的观察者所承受到的光能量是不相同的（无色散光的能量和无色散光发生红移后的红移光能量是完全不相同的）。

To make clear the relationship between Azolla wet-culture yield and energy consumption by yield test of wet cultured Azolla using different artificial light source energy consumptions.
