窄带滤波 meaning in Chinese
narrow band filter
Examples
- The binary optic hyperspectral imaging technology is a spectro - tomographic technique which integrates over a narrowband of the image cube which is a new concept of imaging spectrometer . so the general research direction and the basic research scheme are determined
通过把光谱层析技术和窄带滤波技术相结合，实现了一种新的成像光谱原理，即利用二元光学元件轴向色散的凝视成像光谱技术，从而确定了论文的总体研究方向和基本方案。 - Photorefractive gratings are promising to be applied to wavelength division multiplexing ( wdm ) systems and electro - optic integration due to the advantages of small size , simple structure , easy erasing , high diffraction efficiency , low temperature sensitivity , narrow band filtering and so on
光折变光栅具有体积小、制作简单、易擦除、可以实时处理、衍射效率高、温度响应小、可以进行窄带滤波等优点，其在波分复用系统和光集成方面有着潜在的应用前景。 - Realizing the excellency of nd : yv04 crystal , we use nd : yv04 / ktp firstly in our experimentation . the loss of light with different polarized orientation is different , when it through nd : yv04 crystal . utilizing the case and changing the thickness of ktp crystal by controlling temperature , we get a narrow light filter , so the cavity operates with single longitudinal mode
