In the reading action the effect of the beam on the charged or uncharged area is detected. 在读操作时,则是检测电子束在有电荷区或无电荷区的效应。
While reading the low beam sense status, turn the headlamp switch off then back on. 当读近光感知状态时,将头灯开关转为关,然后恢复为开。
The result shows that the longitudinal and transverse errors are compensable according to the assistant and reading beam, however, at the expense of transmittance loss. 结果表明,对辅助光束与读写主光束强度之比,纵向加工误差与横向加工误差可以互补,但是,要以损失部分透过率为代价;
In the setup for real time writing and reading, the Fourier transform hologram using Cr ∶ SBN crystal as the recording medium, the spatially separated high and low frequency components of the object beam will couple with the reference beam individually. 在用Cr∶SBN晶体作记录介质的实时傅里叶变换全息读写装置中,物光中相对分离的高、低空间频率成分分别与参考光波在晶体中发生二波耦合。
BR film is one kind of excellent nonlinear optical materials. In this paper, we realized all optical Boolean logic based on the relationship among the polarization states of the recording beams, the reading beam and the diffraction beam for the holograms in bR film. bR膜是一种优良的非线性光学材料,利用bR膜中的全息光栅的记录光、读出光及衍射光三者偏振状态之间的关系,在bR膜中实现了全光布尔逻辑操作。
