[光] 全反射
This phenomenon, well known to snorklers, is called total reflection.
这种现象称为全反射, 潜水员都很了解这一点。
A new method was developed for measuring the refractive index based on total reflection.
介绍了一种用于全反射法折射率测量的光学系统。
It is showed that quasi-total reflection would occur when the electromagnetic wave traveled f.
曲线显示当电磁波由电导率大的介质向电导率小的介质传播时,将发生类全反射。
Linearly polarized light will in consequence become elliptically polarized on total reflection.
因此,线偏振光径全反射后将变成椭圆偏振光。
Attenuated total reflection Fourier transform infrared (ATR-FTIR) was used to study the inhibition mechanism.
应用全内反射红外光谱法探讨了复配缓蚀剂的缓蚀机理。
|perfect reflection;[光]全反射
全反射(Total Reflection)是光学中的一种现象,指当光波从高折射率介质(如玻璃或水)传播到低折射率介质(如空气)时,若入射角超过临界角,光波会完全被反射回原介质的物理过程。此时,折射现象消失,光的能量几乎全部保留在原介质中。
全反射的发生需满足两个条件:
$$
theta_c = arcsinleft(frac{n_2}{n_1}right)
$$
其中,$n_1$和$n_2$分别为两种介质的折射率,且$n_1 > n_2$。
全反射(Total Reflection)的详细解释如下:
全反射(又称全内反射,total internal reflection, TIR)是一种光学现象,指光从光密介质(折射率较高,如玻璃)进入光疏介质(折射率较低,如空气)时,当入射角超过临界角,光线会完全被反射回原介质,而不发生折射的现象。
