light wave phase modulation 光频相位调制
The electron oscillates parallel to the electric field and at the same frequency, but it does not necessarily oscillate in phase with the light wave.
该电子以相同的频率来作平行于电场的振动,但此振动不见得和原光波同相位。
The phase velocity of the plasma wave approaches the velocity of light due to the action of the longitudinal electric field.
在这样的纵向电场作用下,等离子体波的相速接近光速。
Modulation of light refers to changing parameters of light wave such as amplitude, intensity, and phase, frequency, polarization, etc. to make it carry message.
光辐射的调制是指改变光波振幅、强度、相位或频率、偏振等参数使之携带信息的过程。
