optical spectrum

基本解釋

Now you take an optical telescope and you look from the ground, and now you see the optical spectrum of the donor.
看一下地面,你會看到，供體星的光譜,知道你會看到什么嗎。
In experiment, we research the optical spectrum and analyze the influence of driven current noise on optical spectrum linewidth of tunable DBR laser.
實驗研究了可調(diào)DBR激光器的光譜特性，并分析了驅(qū)動電流噪音對可調(diào)DBR激光器線寬的影響。
The author takes light source of the rectangle optical spectrum as an example to calculate time relevant degree and briefly describes Fourier's spectroscopy principle.
以矩形譜線的光源為例，計算了時間相干度，簡要介紹了傅里葉變換光譜學原理。

This means more cell towers, more small cells, more Wi-Fi, more advanced technology like LTE and MIMO, more spectrum, and more Ethernet optical fiber links connecting all these wireless and data center nodes.

光譜
Conventional phase retarders are mostly applied to a single wavelength, however achromatic phase retarders can be applied to broader optical spectrum which weaken the dependence of retardation on wavelength largely and operate at an irreplacable action in modern laser technology.
常規(guī)相位延遲器多用于單一波長，而消色差相位延遲器大大削弱了延遲量對波長的依賴關系，可以用于較大的光譜范圍，在現(xiàn)代激光技術中有著不可替代的作用。
